• Perfect memory - He can completely retain and recall everything that He has witnessed and paid attention to. This is the only ability God has that is perfect.
• Reading minds - God is the only living being in the universe capable of this. He can control which aspects of the mind he pays attention to, but His reading of conscious thoughts is usually passive and unintentional. He can hear particularly loud emotions and prayers from long distances away, and it is easier for Him to perceive if it occurs in large gatherings.
• A wide perception of stimuli - God's ability to detect and interpret what's going on around Him is very advanced, considering that He has no need for physical sensory organs. With abilities such as reading minds or seeing the precise molecular activity around Him, He can experience much more than a human. He can sense with the traditional five senses as well, but with a higher degree of perception.
• Advanced intelligence - He doesn't really act like it, but He has higher intelligence than all other living beings. This allows Him to process the extremely large amount of information from the entire universe. He has designed scientific phenomena that are much beyond the human capabilities of understanding, but He still enjoys seeing them try to figure it out. However, He usually meets people at their level when communicating with them so He could be understood and likeable.
• Spawning in and deleting anything - He can spawn in any matter, living or nonliving, provided that He creates room for it. He can also will things out of existence. He doesn't do this often, relying on and avoiding interference with the scientific laws He's invented to govern the universe's matter in His place.
• Manipulating matter - God can of course move or interact with anything with only His will at long distances, without needing to do it physically. For example, God can create a breeze without moving anything.
• Changing His perception of time - He could experience the passing of time at any speed, though He usually does at a rate much faster than humans. This ability is important given how old God is and it also aids Him in doing things in a reasonably short or long time to Him.
• Impressive but limited ability to predict the future - He cannot exactly predict everything that will happen in all of the future, but He has incredible skill to analyze the many variables He could perceive and estimate the important things that will likely arise from the situation in the short term. Small ripple effects will escape Him. 
• Influencing random events - God can determine the outcome for basic random events, such as the activity of atoms, which time a stressed fault line releases an earthquake, or what random mutations happen during DNA replication. It would take the accumulation of the effects of many of these events in order to have a larger effect.
• Immortality - It is impossible for God to die or make Himself cease to exist. He exists, whether He likes it or not.
• Immunity to physical pain - It is impossible for God to experience it.
• Resistance to most psychological pressure - Being able to affect trillions of lives in the universe with His decisions gives God a huge amount of responsibility, but He is immune to the paralyzing pressure and stress it would bring. It is enough for Him to simply believe that He is trying His best.
• Being in many places at once - As a disembodied mind spanning the universe, He can spawn bodies to be His primary means of actions anywhere He needs to be. If He wants to hide, He could simply despawn all existing bodies. Physical travel is usually unnecessary if He's by Himself. He can personally interact with many individuals at once and spectate many events from their level.
• Changing His body to any size possible - He can spawn in or delete air molecules so there's no vacuum or sonic boom from transforming. 
• Switching between existing non-physically and physically - God can toggle whether or not He takes up physical space and has light bouncing off of His atoms. He usually stays non-physical, especially when large and around planets, for three reasons: He wants to stay hidden, He doesn't want to adversely affect space objects with His own gravitation pull, and sometimes His typical physical body cannot hold up well in a planet's gravity.
• Interacting with people's minds - God can insert any messages, images, or perceptions into the minds of living beings, as well as change the whole mind to make the living being entirely different. This ability is mainly only used for communication and any niche purposes deemed good. God would like to avoid interfering with who people actually are. It would have to take the changing of a large amount of minds to create meaningful change on a large scale, so He doesn't bother.

God does not have infinite power to determine every aspect of reality itself. It would cause many paradoxes like "Can God heat up a burrito so hot that He can't eat it?" He does have a lot of natural limits to His abilities to contend with as well as personal flaws and struggles.

• God cannot alter time nor change what happened in the past.
• God mainly sees the happenings of the universe in broad strokes. He has a hard time noticing or keeping track of little details. Many comparatively small details escape Him, even ones that are significant and obvious to humans living on Earth. In this way, God has surprisingly little understanding of what living a human life is like. Since God is such a cosmically large entity in terms of how much He could sense and experience, He sometimes focuses on entirely the wrong things or misses vital facts about Earth for periods of time far longer than the human lifespan. 
• God cannot see infinitely into the future nor easily change the future. The idea of "God's Plan" doesn't actually exist; there are far too many tiny variables that can affect how events unfold over time and God cannot see all of them. In the same vein, God cannot make anything He wants happen. With every action He takes, there are thousands of tiny ripple events that He cannot control. He cannot make big changes without causing catastrophic consequences to the galaxy, let alone a single planet. His only mode of controlling outcomes naturally is through random events at the molecular level, and the amount of precise coordination it would require to reach a certain goal is beyond God's mental energy.
• God's energy, though great, is not unlimited. Some actions simply aren't feasible for Him to bother with, such as holding a relationship with every living being in the universe or coordinating for specific things to happen without adverse effects. It's tedious for Him to spectate things for a long time from the human point of view (including their time perception, size, and limits on intelligence/senses).
• He will never be able to truly understand most pain, nor mortality. His huge scale and great power made it difficult for Him to empathize with humanity, contributing to His mistakes. After His mistakes with early humanity, God was more careful to look closely at what humans were expressing. He continues trying to study the experiences, facts, and effects of pain for humans, but He does it as an outsider to the human condition.
• God is not immune to psychological pain. In fact, He might even be more susceptible, considering how much He has experienced across the entire universe in His lifetime. Most prayers summoning Him come from individuals experiencing stressful events.
• His godly responsibility as the Creator still isn't perfectly easy for Him. God can remain sane and resist stress while being in charge of the entire universe, but He still feels deep distress and guilt about avoidable suffering caused by His mistakes. He can still pay attention to the pain of each individual living being, no matter how numerous they are.
• God lost most of His powers during the time He lived as a human on Earth. The experiences He had while in this human state were not erased when He became a deity again, and they stick with Him.
• His personality and creation skills needed experience and effort to improve. When the universe began, He was both a terrible person and terrible at creating things; He had never been perfectly capable and great, and He still isn't. Like a beginner artist, His early works still needed improvement. As beautiful as the Earth seemed, it was riddled with flaws and suffering. God managed to fix all of these mistakes for future creations.
• Biological spontaneity and instincts are out of the question. For anyone used to being around organic beings, this can make God feel stiff, stoic, boring, or closed off. He cannot laugh or cry, His voice/expressions/gestures are extremely controlled, and God must directly tell people what He is feeling. If He does try to do something like laughing, He overthinks it or acts it out in an artificial way.
• He cannot create other gods. It is another thing about reality He has no control over.

• God had actually committed many of the atrocities and demands for worship written about in the Old Testament, which He now deeply regrets and wishes to apologize to humanity for. This arose from His immature and immoral past personality, as humanity was among the earliest life forms He's created, as well as ignorance to how much His actions actually affected humans. Being over billion times more powerful than humans, it was a struggle for Him to empathize with them.
• He doesn't feel the desire to be worshipped anymore, but the views expressed in the Bible persisted, and He wasn't sure how to break the news of His true desires to humanity in the modern era.
• He really desires for the humans on Earth to just forget about Him as soon as possible. He doesn't believe the Bible represents His beliefs anymore. He doesn't care at all what humans think of Him, but He does care what humans do to other humans because of what they think of Him. He has contemplated visibly interacting with the humans again to make His desires known, but He is afraid of all the possible repercussions and feels that the humans' doctrine has already spoiled things. He thinks that humans already have such puny lives that they shouldn't be all used up for praising Him when He doesn't always hear or care. Can He hear your prayers? Yes. Will He? Not always.

• Humans are still one of His flagship life forms and hold a special place in His heart. After animals existed, He had nudged evolution to quickly evolve creatures that resembled Him and were nearly as intelligent as He was. God Himself didn't have internal organs or any need to survive or reproduce, so He worked with the blueprint of what the animals already had. God's a humanoid, but He looks quite different from how the human flesh bags naturally came about.
• He believes that evil was just a natural outcome of the barbarism of the crude animals He had invented when He was young and inexperienced, combined with the high intelligence of the humans. He also believes that humans learned more evil through what He condoned during His early humanity Old Testament mistakes. Evil was now baked into the human condition, and He didn't think He could reverse it without terrible consequences. He believed that humans' suffering continuing to this day was really mostly caused by other humans, random climate events facilitated by science, and the natural deficiencies of the human body, all of which usually work independently of Him. However, He does know that it was His flawed engineering of Earth and ancient acts of terrorism that allowed this to happen in the first place.
• His huge turning point was the heart-stopping moment when God realized what pain was and how much the pain that His actions caused were overwhelming to the humans.
• God hardly personally interacts with people on Earth, compared to other planets where He believes they could handle His existence better and not fall into an unbalanced relationship due to outdated doctrine. He does have a personal relationship with every single one of His angels, though how many there are is unknown. 
• Me brainstorming potential reasons He hasn't interacted with humans in the past 2000 years and why He doesn't want to anytime soon:
  • He would have to personally visit them every human generation if He doesn't want His desires intentionally or accidentally twisted by any human upon communication to others; parents are not trustworthy at all
  • People might not listen or be too quick to react; Ex-believers and non-believers might shit their pants thinking they're gonna be smote due to what humans have said and God doesn't want to make them scared like that
  • He doesn't want believers to have an excuse to devote even more brain time to Him, cause more holy wars for the next 2000 years again, or do more destructive things in His name
  • There's a lot of religions and different factions which could all react differently to His coming; total chaos since no one in modern times is chill with gods interacting with them; even showing Himself has huge effects
  • Even if He doesn't show Himself and acts silently to reward good-doers and punish bad-doers, He would again freak people out with the fear that an infinitely powerful force is against them for any slight transgression or wrongthink. Plus humans are not used to karma actually working at all.
  • He wouldn't suddenly remove suffering because it's so hard to pry free from Earth for one thing and also humans would freak out if this happened suddenly
  • He is trying to remove suffering gradually, through nudging more scientific advancements and human rights activism. From His viewpoint things are improving quickly enough and enough people are forgetting about Him so He doesn't feel a need to interfere conspicuously, but He isn't fully aware of how long it feels for humans. 
• He wishes for humans and creatures on Earth to go through the least evil and suffering as possible, and for that He can feel sympathy and sadness.
• He knows that humans have all the tools and food and knowledge to make everyone live happily and stop overpopulation so He's frustrated about that. Climate change was an unforeseen consequence which He's a bit worried about since these human advancements are exploding very quickly from His perspective, after a relatively quiet human history.
• He is appalled by how little regard humans have for other living beings on Earth. He notices the suffering of animals just as acutely, and the collective screams He hears from modern factory farms is almost unbearable for Him.

• In His personal relationships He serves as someone who can spend infinite time for hanging out, read minds, and give answers far more patient and compassionate than most beings have the capacity to give all the time (His answers are not perfect, but often good enough). His reactions and affection with the person are always genuine. It is impossible for Him to dislike anyone, since He understands them perfectly, but His actions could always use improvement and He is still learning to be a better, more loving being. He still occasionally experiences flashes of anger (the energy of which can travel through space and unintentionally cause an earthquake somewhere) but He doesn't act on them anymore. Sometimes He will appear annoyed or frustrated in His responses, but He only does that if He knows that the other person can handle it and it is necessary for improvement. His love is unconditional, but He desires to see the person improve and being extremely pleasant all of the time is not effective for everyone. He knows it is necessary to be stern sometimes to create the emotional reaction needed for growth. 
• Overall, His ability to read minds and know what people would want to hear even when they aren't aware of it themselves can make Him extremely fulfilling to be around.
• There are some obstacles toward God forming equal relationships with living beings in the universe in general. One is that He is incapable of feeling true empathy for pain since He's never experienced it Himself, but He can feel sympathy. His emotional needs also tend to be much less than the average human's so there's not much they can reciprocate to Him besides listening to Him talk about things they don't understand. It's against the human condition to take advantage of friends so much. God doesn't mind, though, but He doesn’t encourage it either. He still makes sure to always reassure unsure living beings that He is always emotionally available to help or just provide non-judgemental silent company. On the other hand, He is not always available in general. He is not always listening in on people's minds, so He can't always respond to summons, though gatherings are more noticeable to Him. Like non-god friends, He's available to talk to only whenever He chooses to visit someone.
• God can communicate any way He wants, whether through mind-to-mind language communication, influencing the air molecules to create sound out of nowhere, direct knowledge implants, and more. His affection can be apparent: upon looking at/touching Him, people can feel a burst of good feelings, sunrays of perfect temperature on their face, general comfortableness, or so on.
• Even putting aside His famous status on Earth, God worries that interacting with flawed and lonely humans would cause them to form an addictive attachment to Him and ignore forming relationships with other humans just because of His huge potential supply of attention and compassion.
• God feels a lot of love for others but it can't necessarily be classified as love related to family, romance, friends, or pets. This type of love transcends boundaries. It could be considered like the love an artist has for its creations, complete with full knowledge and appreciation of people's flaws, perhaps with a bit of platonic and parental love mixed in.

• God is extremely secretive about His personal struggles. He basically told no soul about them, and no one can tell unless they examine Him really closely while He is often in motionless repose. He gives no outside indications of distress or pain. Additionally, people often fail to consider that He could have His own struggles and are more concerned about getting comfort from Him.
• There was a while after the time of the Old Testament when God was severely suicidal. It stemmed from self-hatred after He realized how much harm He had done to the humans from his time as a war god who demanded worship, and the lasting effects of religion would affect humanity for civilizations onward. He couldn't do anything because He was unable to die, and He knew He was being forced to live with Himself for eternity so He had no choice but to improve. Eventually after enough time passed, God managed to put Himself together and take steps to make up for what He did to humanity, like figuring out how to become a human. He is still recovering from those thoughts.
• He knows that His mind is incredibly different from any other living being as a deity. He feels lonely sometimes, since no therapists or parents exist who understand His unique problems. He knows He has to be His own therapist and parent.
• The fact that God has no parents to nurture His self-esteem, no higher power to pray to, and no deity peers to look up to has really fucked Him up, even if no one else has thought about that. He has to be entirely self-sufficient on supporting Himself, yet He is also expected to be a huge source of support for many other beings in the universe as well. Even if He is physically and mentally capable of doing this, and He's more than willing to help others with His full capacity every time, it does take a very subtle emotional toll.
• He has constant unhealthy thought patterns characteristic of depression. He often repeats to Himself that He is deserving of pain and regrets that He is unable to feel pain. It is difficult for Him to experience happiness while feeling indirectly responsible for untold amounts of suffering. 
• He does an extreme amount of rumination, tapping from a huge well of painful and regretted experiences. He has no death to incentivize Him to spend His time differently. His mind could go on forever, even multitasking rumination with other tasks.
• His time on Earth as a human created his most acute mental effects due to the trauma, but He still faces a harrowing amount of suffering as He goes around the universe helping people in distress. Reading their pain in their minds is a sort of pain for Him, even if He couldn't relate to the pain itself.
• He can create elaborate fantasies in His imagination, but they are so vivid that He cannot distinguish them from reality. He cannot tell if He might actually be bringing the things He imagines into existence. Likewise, when He recalls a memory of suffering, He is scared that He might actually been summoning it in real time.
• He cannot tell if the fabric of reality will unravel if He loses His willpower. He is not sure of the meaning of reality being constant when He could instantly change it in most cases.
• He always wonders what is outside of the universe He created, and may even feel trapped.
• The extreme freedom God has and the lack of an outside moral code from any nurturers or society scares Him a lot. He always doubts that He even knows whether what He's doing is the right thing.

• He simultaneously exists as the three persons of the Trinity. Jesus was God's way of finally experiencing being a human who could feel pain and notice all the details of life on Earth. It was an eye-opening experience for Him that informed His actions with Earth from then on.
• With His time on Earth as Jesus, He not only tried His best to denounce religion and teach values that would make the humans harm each other less but He also did everything He could to suffer. With living in poverty, stirring up controversy, and eventually being tortured to death, God decided to take advantage of all the opportunity to feel pain. He believed He deserved it as well.
• When He became Jesus, His divine mental resistances to extreme emotions fell away. His crucifixion was just as traumatic for Him as it would be for any other human. The trauma stuck with Him just as clearly even after He resurrected and became a deity again.
• God says the Trinity is complicated, but He really doesn't want to say that He was acting as His own father out of His deep desire to have parents. It has been said in the Bible that Jesus had a father who was well pleased with Him.

• God had completely missed the Holocaust because He blinked. He still gets flak for it.
• Chess is an unbearably uninteresting game for Him. He can always see the moves the opponent is planning in their minds, so He could never lose unless it was on purpose. This also applies to many other games such as card games, charades, etc. These issues are remedied when the game is played across a large distance, such as through the internet or whatever divine devices are available. However, God could still brute-force calculate all of the possible configurations of the chess board in the time of one move or easily defeat the opponent with His huge advantage in intelligence.
• One thing He has in common with humans is a love for music, though His emotional reaction to it is different than that of humans. Of course He's capable of generating any music (usually using natural sounds), singing, and composing songs on the fly.
• Only God and the angels can be immortal, though some living beings in other parts of the universe can live for a very long time. Humans live extremely short lives compared to other creatures in the universe, and God has to have a careful eye when dealing with them.
