Too long for my laziness cofty. I've been involved with TONS of threads dealing with the proof of God. It goes nowhere. For example, if I was to tell you (and this has NOT happened... :-) ) that God spoke to me and told me what would happen in the future, you would say that I am delusional and you would not believe my claims. So I cannot argue with you using personal experience.If I was to tell you that I know God exists because information cannot come from non-information, so information can only be generated by prior information, you would either ignore this FACT or come up with another argument.
But if you want it, well here is what I think about the proof. Please bear with me as I get to the point:
I believe that the law of logic exists. An example of a law of logic is the law of non-contradiction. This law states, for instance, that it cannot both be true that my car is in the parking lot and that it is not in the parking lot at the same time, and in the same way. I belive in the law of mathmatics. For example, with the law of addition we know that if you take 4 things and add them to 3 things, you end up with 7 things. I believe in the law of science. An example of a law of science is the law of gravity. Using the law of gravity, we can predict how fast a heavier than air object will fall to the ground given all the factors for the equation. I also believe that there are absolute moral laws. Whereas some laws like those that govern science, and mathematics describe reality, and how things do behave, absolute moral laws 'prescribe' how humans ought to, or ought not to behave.
So what do I believe ABOUT these laws. Are these laws material, or are they immaterial? In other words, are they made of matter, or are they 'abstract' entities? - are they physical or non-physical things? They are immaterial non-physical things. So do I believe that these laws are universal or individual? Is 2+2 = 4 only true to ME where I am at, or is it a universal truth? I believe they are universal. And I believe that these laws are unchanging.
Universal, immaterial, unchanging laws are necessary for rational thinking to be possible. Universal, immaterial, unchanging laws cannot be accounted for if the universe was random or only material in nature.
The Bible teaches us that there are 2 types of people in this world, those who profess the truth of God's existence and those who suppress the truth of God's existence. The options of 'seeking' God, or not believing in God are unavailable. The Bible never attempts to prove the existence of God as it declares that the existence of God is so obvious that we are without excuse for not believing in Him.
Romans 1 vs. 18 - 21 says:
The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness, since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God's invisible qualities - his eternal power and divine nature - have been clearly seen, being understood from what has been made, so that men are without excuse. For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.
The God of Christianity is the necessary starting point to make sense of universal, abstract, invariant laws by the impossibility of the contrary. These laws are necessary to prove ANYTHING. Therefore...
The Proof that God exists is that without Him you couldn't prove anything.
Note that the proof does not say that professed unbelievers do not prove things. The argument is that you must borrow from the Christian worldview, and a God who makes universal, immaterial, unchanging laws possible in order to prove anything.
This type of logical proof deals with ‘transcendentals’ or ‘necessary starting points,’ and the proof is called a ‘transcendental proof.’ Any contrary view to the God of Christianity being the necessary starting point for rationality is reduced to absurdity. You have to assume God in order to argue against Him.
