Arguments For/Against the Existence of God

HideShow resource information

Cosmological Argument (For)

  1. Things exist.
  2. It is possible for those things to not exist.
  3. Whatever has the possibility of non existence, yet exists, has been caused to exist.
    1. Something cannot bring itself into existence, since it must exist to bring itself into existence, which is illogical.
  4. There cannot be an infinite number of causes to bring something into existence.
    1. An infinite regression of causes ultimately has no initial cause, which means there is no cause of existence.
    2. Since the universe exists, it must have a cause.
  5. Therefore, there must be an uncaused cause of all things.
  6. The uncaused cause must be God.

Strengths and Weaknesses Of The Argument

The strengths of the Cosmological Argument lie in both its simplicity and easily comprehensible concept that there cannot be an infinite number of causes to an event.  Some arguments for God's existence require more thought and training in terms and concepts, but this argument is basic and simple.  Also, it is perfectly logical to assert that objects do not bring themselves into existence and must, therefore, have causes.

One of the weaknesses of the argument is that if all things need a cause to exist, then God Himself must also, by definition, need a cause to exist.  But this only pushes causation back and implies that there must be an infinite number of causes, which cannot be.


Also, by definition, God is uncaused.

Teleological Argument (For)

The Teleological Argument is also known as the "argument from design."  Quite simply, it states that a designer must exist since the universe and living things exhibit marks of design in their order, consistency, unity, and pattern.

  1. Human artifacts are products of intelligent design.
  2. The universe resembles human artifacts.
  3. Therefore the universe is a product of intelligent design.
  4. But the universe is complex and gigantic, in comparison to human artifacts.
  5. Therefore, there probably is a powerful and vastly intelligent designer who created the universe.

Strengths and Weaknesses Of The Argument

This argument is simple to understand and has merit, since humans are designers by nature and it is natural to think in terms of things having purpose.  It is also consistent with Rom. 1:20: "For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse."

I think the teleological argument carries weight because it is consistent with Scripture.  The Bible states that we are made in God's image.  Therefore, there are certain things with which we will resonate.  Even though the unbeliever suppresses the truth of God in his unrighteousness (Rom. 1:18-32), the truth is still there.

Additionally, evolutionists have difficulty accounting for apparent design in objects like the eye, the heart, and the brain where many different parts come together to form the whole.  These individual parts have no purpose except in the function of the whole.  How can evolution account for these detailed congruent occurrences?  So far, it can't

.The idea that the universe is designed is subjective.  Different observations in the natural world can produce different theories to account for their existence.  Also, this proof is built upon an analogy.  If we find things in the universe that are chaotic, then by analogy, that would imply there is no designer.

Ontological and Moral Argument (For)

Ontological - This basically refers to the fact that once we have accepted that there is an omnipotent and omnibenevelent God, it is impossible for him not to exist. This is because we would imagine him as the perfect being, could not fail to exist.

Moral – all moral laws come in the form of commands, these commands tell you what to do, what is right and wrong, etc. There has to be a commander who commanded us to behave in moral ways.

Arguments Against

Evil – this argument argues that if there is evil there cannot be an omnibenevelent God, and if there is suffering there cannot be an omnipotent God.

Emotional crutch – believing in God is just a way of dealing with the reality that there is no God, and that helps them with emotion problem stress, etc.

Paradox of the stone – if God is omnipotent then is there a rock that he can make that is too heavy for him. If he can then he is not all powerful because he can’t lift the rock. If he can’t then he is not all powerful because he cannot create a rock that heavy.
