Proof of God

formal rules of logic
At all times and in all places, most people seem to have built-in knowledge of the designer-creator God, and it is rare that anyone asks for proof of God.
Some people, whether sincere or just for argument, say it's impossible to prove that God even exists.
Actually, IT IS POSSIBLE to prove the existence of God by universally acknowledged RULES OF LOGIC, summarized below.
(However, for a Christian, powerful life-changing proof does not come from logic but from actual experience – a personal relationship with God through Jesus Christ.)


more than blind faith


First we apply a law of logic known as the law of the excluded middle, which states that a thing either IS or IS NOT.

If there were a time when nothing existed, then nothing would exist today. Something and nothing are mutually exclusive. Something cannot come out of nothing because nothing is always nothing.

Since something now exists, it follows that the something existed before nothing and is independent of nothing.


Again, applying the law of the excluded middle, we ask if the something is material (matter) or non-material (spirit) in nature:

We now know that the universe began at a moment in time with a colossal burst of energy (Big Bang).

First Law of Thermodynamics: Energy cannot be created or destroyed; the total quantity of energy in the universe is always constant.

Second Law of Thermodynamics: As energy is transferred or transformed, more and more of it is wasted (unusable) and it gradually degrades into entropy (disorder). One entity or universe giving birth to another cannot avoid the law because each cycle has less usable energy than the previous cycle.

Thus, the something is non-material (spirit), otherwise it would not exist because through eons of time it would have exhausted all usable energy.


Einstein's Theory of General Relativity, universally accepted as true, states that time is linked to matter and space and that time itself began concurrently with matter and space.

Since the something existed before both matter and time, it follows that the something is timeless.


EVEN IF all the atoms and sub-atomic particles in the universe came into existence by themselves from nothing, what is the probability that these random particles could arrange themselves in place, and hold themselves in place, to form our fine-tuned universe without any guiding intelligence and power?

The probability calculation for random chance is so incredibly large that it becomes infinite and nil.

If the probability of all the atoms and sub-atomic particles in the universe forming and maintaining our fine-tuned universe without intelligence and power is nil, then the something is infinitely intelligent and infinitely powerful.


Life is essential for decision-making. If there were no intelligent exercise of will to bring something out of nothing, everything would remain nothing.

Life cannot come from non-life, so life on earth is from transcendent life outside of earth.

The SOMETHING = Spirit + Timeless + Infinite + Alive = GOD

Rules of logic lead to
definition and reality of God

'Then who made God?'
This is usually intended as a gotcha question. For any answer, the question can be asked over and over again to infinite regress.
Of course, only God knows, and our human minds are not capable of comprehending thoughts at that level.
However, the question actually strengthens the case for God:

Since the creator is more powerful than the created, each iteration back in time would require a more and more powerful God. Therefore, the question does not negate God, but raises God to a higher power each time asked.
