Is God All-Powerful? Can God or Anything Truly Be Omnipotent?

#christianity #god #islam #religion

Omnipotency is the power to do anything at all - "all-powerful". In monotheistic religions such as Christianity and Islam God is held to be all-powerful. It is hard to imagine that any omnipotent being could be anything other than a single monotheistic God. Omnipotency implies other super-powers because if you are all-powerful then you have the means to instantly uncover any and every fact, so it also infers omniscience. Not only that but, in order to have the ability to do anything, you need to know everything. You can't change reality (for example, by making a cup appear out of thin air) without knowing the precise and accurate detail of how every atom and subatomic particle in a cup should be positioned and the detail of how every intrinsic force of nature works. Omnipotency and omniscience go together. Omnipotency requires omniscience.

Interestingly the very concept of omnipotency has such theological and philosophical difficulties that it seems that it is a self-contradictory and impossible concept, especially when combined with other properties such as omniscience and free will. God itself is constrained by the laws of logic and rationality - it can't make a square circle, or create an object that it can't destroy, or create other omnipotent beings. In order to create and to act, God's thoughts must be rational and logical; hence, God itself relies upon the pre-existence of logic in order to create anything according to any thought out plan. The strength of these logical rules imply that nothing can be omnipotent.

1. Logical Limitations: An Omnipotent God is Impossible

There are some commonly stated limitations to the very concept of omnipotency, meaning that some qualifications need to be made against the idea of an all-powerful God:

  1. Irrational and illogical actions such as creating a "round square" or making 2+2=5, appear to be impossible even for an all-powerful God. So many say that "all-powerful" means only the ability to do all logical non-contradictory actions.1

  2. Self-limiting actions such as making itself non-existent, or, removing its own power of omnipotency, are often said to be impossible for an all-powerful being. If it chose to make itself unable to do a particular action then it would be a simple gesture for this being to re-instate its power. For example, if the all-powerful God knows that in the year 2050 it will cause an Earthquake, but, in the year 2040 it removes its own power to cause natural disasters, it can of course do two things, (1) use its omnipotency to give itself the power again, or (2) in 2030 to jump ahead in time and do it before it removed its own ability. Also if such a being decides "I shall for all time not have the ability to do something", then, it can only do that action if it does have the ability to do it. This self-negation causes an impossible time-continuum contradiction. It thusly seems impossible for it to stop itself from performing any action.

  3. There can only be one omnipotent being, otherwise, their two independent wills would limit each other's power. By definition, both would have to "get their own way" all the time in order to continue to be all-powerful. In other words, they could never effectively disagree. Therefore there can only be one omnipotent being which means that any omnipotent being cannot create another omnipotent being - yet another thing than an "all-powerful" God cannot do!

Finally, the three most damning limitations:

  1. God Cannot be Responsible for Creating Logic Itself:

    In order to create, to think, God's thoughts must be more than random. To create the universe and its laws, God must be able to think logically. If it can't think logically, then, the laws of the universe were simply random, and the Universe might as well been self-created in an atheistic manner. In other words, for God to exist, God's thoughts must have always been ordered in a logical manner otherwise God could never have created order from chaos.

    Kepler, one of the great minds in the history of science, came to similar conclusions about geometry, but didn't go as far as to say that it preceded God:

    Geometry existed before the Creation. It is co-eternal with the mind of God... Geometry provided God with a model for the Creation... Geometry is God Himself.

    Johannes Kepler
    In "Cosmos" by Carl Sagan (1995)

    Kepler was assumedly counting mathematics and the general rules of the universe as 'geometry'.

    This means that logic is a precursor to God. Logic, with its simple relations and rules that lets thought itself be ordered, must have existed independently of God's creative power. God could not have created the logic because requires logical thoughts to do any meaningful creating. See: The Universe Could Not Have Been Created by God: The Failure of First Cause Arguments.

  2. An all-powerful god cannot be benevolent. Responsible for making every aspect of evil and suffering possible and for creating the long chain of cause and effect that results in disasters and influences people to choose wrongly, god is so absolutely responsible for all evil and pain that it renders it amoral at best, and at worst, immoral. See: The Problem of Evil: Why Would a Good God Create Suffering?.

  3. God contradicts free will. If a being is all-knowing, then, it knows exactly what actions it itself will make at any point in history. This removes the ability of the God to actually change its mind, alter the grand plan, or in other words, to exercise free will in any way, as the all-powerful and all-knowing being is guided purely by a deterministic fate based on infallible knowledge of its own future actions. Hence, many say that an all-knowing and all-powerful being cannot be a moral being and is probably an unconscious automaton (ergo, not divine). See: God Has No Free Will: 2 Proofs

These limitations on omnipotency have built up to form quite a list of things an all-powerful being cannot do. "All-powerful" can't mean what it says in any simple way. Omnipotency is best not described as "the ability to do anything", rather as "the ability to do the maximum number of possible actions within the confines of logical impossibilities and self-limitations, except the creation of other beings that are also super-powerful, but, this power cannot co-exist simultaneously with the power of omniscience (being all-knowing) and free will nor benevolence. Also, omnipotency depends upon the ability to think straight and therefore requires the pre-existence of logic; ergo an omnipotent being cannot be the reality-creating first cause of existence".

The resultant being, if all-powerful, is the shallow wreckage of an amoral entity, bound by such severe limitations on agency that ultimate creative power, moral agency and free will are all removed. An omnipotent being is simply impossible - the closest thing that could exist is an amoral very-powerful automaton.

2. The Problem of Evil2

#determinism #evil #god #life #philosophy #religion #suffering #theodicy #theology

If God is all-powerful and all-good, it would have created a universe in the same way it created heaven: with free will for all, no suffering and no evil. But evil and suffering exist. Therefore God does not exist, is not all-powerful or is not benevolent (good)3. Such arguments have been used by many philosophers as evidence against belief in god4,5. A theodicy is an attempt to explain why a good god would have created evil and suffering. The most popular defence is that it is so Humans could have free will. However the entire universe and the natural world is filled with suffering, violence and destruction so any Humanity-centric explanation does not seem to work.

"The Problem of Evil: Why Would a Good God Create Suffering?" by Vexen Crabtree (2011)

Primitive gods could literally and physically fight against evil. But as philosophy and science taught us the true depth of words like 'creator god' and 'creation', and we understood more and more of the psychological, incidental and mechanistic causes of apparent 'evil', it became quite obvious that the whole system was designed with the possibility for 'evil' in its very fabric. "To increase the power of an anthropomorphic deity until it is absolute is to increase his responsibility until he is amoral"6. Omnipotency is incompatible with benevolence.

3. Can God Create a Rock So Heavy That It Can't Lift It?

This question is often cited as a disproof of omnipotency. If God can't create such a rock, then, God can't do anything, so is not all-powerful. If God can create a rock it can't lift, then, it is not true that God can lift any rock, therefore, God is still not all-powerful. However the question is merely a trick. Consider what it means in practical terms. God can lift an infinite amount. The question is saying, therefore, "Can God create a rock with a weight greater than infinity?". Of course, this question is logically absurd. The question is wrong and illusory and depends upon an illogical concept of "greater than infinity".

4. Is God All-Powerful According to the Christian Bible and Qur'an?

#christianity #islam

Islam: The Qur'an frequently states that God 'has power over all things' and 'is able to do all things'. I know of no verses in the Quran that contradict this. Here are examples from the first five surahs of the Qur'an: 2:20,2:109; 3:189; 4:85,149; 5:17,5:19,5:40, and 5:120.

Christianity: Unlike the Qur'an which asserts constantly, clearly and unambiguously that god is all-powerful, the Bible contains very little direct commentary on the scope of God's power. Verses on that topic are mostly indirect. We can infer that God is all-powerful because Genesis says God creates the world and the heavens in 6 days, etc. But this isn't necessary omnipotence: the fundamental laws of physics, the dimensions including time, etc, are all important parts of creation but not mentioned by the Bible. The God of the Bible is clearly very powerful and creative, but, is not for certain all-powerful.

God is All-PowerfulGod is Limited

Direct Evidence:
Genesis 35:11 and Revelation 19:6:God is almighty (often translated as all-powerful).
Matthew 19:26, Mark 10:27, Luke 1:37: All things are possible with God.
Luke 18:27: "The things which are impossible with men are possible with God".

Indirect evidence / commentary from Humans:
Genesis 1:1-3: "In the beginning God created the heavens and the earth [...]". Being a creator of these things does not necessarily mean God has power over all creation, but, it would still be a sensible assumption.
Genesis 18:14: "Is any thing too hard for the LORD?"
Jeremiah 32:17,27: "Ah Lord God! ... there is nothing too hard for thee. [... God says] "is there any thing too hard for me?"
Isaiah 40:28: God is creator and tireless.
Job 42:1-2: Job says he knows God can do anything
Some translations of Malachi 2:16 have this verse refer to God as "the all-powerful God of Israel". But most translations don't have the "all-powerful" bit.
Psalm 66:5-7: "God rules by his power forever", but, so all non-omnipotent rulers rule 'by their power'.
Hebrews 1:3: God 'upholds all things'.

God Cannot Lie:
Psalm 119:89, Hebrews 6:18, Titus 1:2, 2 Timothy 2:13

God Can't Be Tempted:
James 1:13: I.e., God has no free will to act evilly.

The Crucifiction Facade
If God required Jesus and the sacrifice of Jesus in order to forgive sin and the like, then God is not omnipotent. If God is omnipotent, then, it did not need the crucifixion for any purpose at all.

Can God Defeat Iron Chariots?

Judges 4:13-16: Sisera gathered nine hundred chariots, but the LORD defeated them for Deborah and Barak, whose 10,000 men then killed all of Sisera's men.

Judges 1:19: "And the LORD was with Judah; and he drave out the inhabitants of the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron."

5. The Ineffectiveness of God to Answer Prayers2


People don't really believe that God can, or will, do anything as the result of prayer. It seems odd, given that many people think they believe in prayer, to announce that many of them don't! A series of studies by Justin Barrett focused on asking people which of three things they might pray for as a result of an imminent disaster7. For example, if a ship in the middle of an Ocean was struck and was sinking, would they pray for (a) God to enable the ship to float for longer with a broken hull, (b) for God to let the people survive for longer in the deadly icy cold waters, or (c) for a nearby ship captain to have a sudden idea to change course and therefore rescue the people. Most people pick the third type of prayer: this is a prayer in which human action saves the day - God doesn't interfere with the physics of the ship nor with the biology of the victims of the accident7. A change in human action saves the day. This is because those who pray subconsciously think that it is their own magical words that are enacting the change, and not the creator of the universe.

Barrett was careful to make all these possible interventions equally salient, and though they are all trivial for an omnipotent god, most subjects spontaneously chose the third kind of option [... as] it is easier for a person [who is praying] to change people's mind than to correct or reorient physical and biological processes. But note that this expectation would be irrelevant if God's great powers were the most salient [facilitator].

"Religion Explained" by Pascal Boyer (2001)7

Religionists are apt to describe confusing unknowns as the work of God. Physics and biology have long since been thoroughly understood by science8 and have lost any mystical or spiritual appeal. No longer do gods push the sun and moon around the sky, nor cause thunder. The human decision-making process though, because neurological studies in cognitive psychology are not well known (or understood) by the populace, means that our culture still retains the idea that God can play a part in this process. This is the "god of the gaps" phenomenon. Deep down, many theists understand that God's power is not real; but they still retain the secret, subconscious and superstitious belief that the magical words and the well-wishing of a prayer might still be powerful enough to change a human's actions, even though they don't think prayer could change purely physical processes. When it comes to complicated biological factors where there are statistics involved (i.e., cancer and disease), many theists again think that prayer might work. This is especially true for minor, non-biological ailments, where psychological effects play a big role (i.e. psychosomatic effects), meaning that human agency is still felt to be important (and manipulatable).

6. A Powerful Being Can Easily Fool Us Into Thinking it is Omnipotent

Any powerful, unearthly, being could appear to us to be omnipotent. It could trick minds, perform tricks, even cause floods and inspire books to be written, but, we would have no way of knowing if it was truly all-powerful or merely very powerful. Arthur C Clarke famously wrote 'Any technology, sufficiently advanced, will seem like magic' and likewise, any particularly powerful being can seem as God to us. Assuming that God is all-powerful simply because it is said to have facilitated miracles is not a sensible extrapolation.
