The only proof for the existence of God is that without God you couldn't prove anything.
— Cornelius Van Til
Perspective Proof That God Exists quotations
If God were small enough to be understood, He would not be big enough to be worshipped.

It is the final proof of God's omnipotence that he need not exist in order to save us.

"I refuse to prove that I exist" says God, "for proof denies faith, and without faith, I am nothing." "Oh," says man, "but the Babel Fish is a dead give-away, isn't it? It proves You exist, and so therefore You don't. Q.E.D." "Oh, I hadn't thought of that," says God, who promptly vanishes in a puff of logic.
There are no ordinary people.. it is immortals whom we joke with, work with, marry, snub, and exploit.
The argument goes something like this: "I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing.

A man does not call a line crooked unless he has some idea of a straight line.
Atheism is a crutch for those who cannot bear the reality of God.
It is not the objective proof of God's existence that we want but the experience of God's presence. That is the miracle we are really after, and that is also, I think, the miracle that we really get.

Absence of evidence is not evidence of absence.
For when we cease to worship God, we do not worship nothing, we worship anything.
I prefer an attitude of humility corresponding to the weakness of our intellectual understanding of nature and of our own being.

Oh dear,' says God, 'I hadn't thought of that,' and promptly vanishes in a puff of logic.
The proofs of the existence of God are to such an extent fallen into discredit that they pass for something antiquated, belonging to days gone by.
It is certain that those who have the living faith in their hearts see at once that all existence is none other than the work of the God whom they adore. But for those in whom this light is extinguished, [if we were to show them our proofs of the existence of God] nothing is more calculated to arouse their contempt. . . .

If no God, mankind is a set of bi-pedal carbon units of mostly water. And nothing else
As we survey all the evidence, the thought insistently arises that some supernatural agency-or, rather, Agency-must be involved. Is it possible that suddenly, without intending to, we have stumbled upon scientific proof of the existence of a Supreme Being? Was it God who stepped in and so providentially crafted the cosmos for our benefit?
I have repeatedly said that in my opinion the idea of a personal God is a childlike one.

I was at this time living, like so many Atheists or Antitheists, in a whirl of contradictions. I maintained that God did not exist. I was also very angry with God for not existing. I was equally angry with Him for creating a world.
There are those who hate Christianity and call their hatred an all-embracing love for all religions.
The real attitude of sin in the heart towards God is that of being without God;
it is pride, the worship of myself, that is the great atheistic fact in human life.

A heathen philosopher once asked a Christian, 'Where is God'? The Christian answered, 'Let me first ask you, Where is He not?'
The idea of a personal God is an anthropological concept which I am unable to take seriously.
I don't know about you, but I call impromptu vomiting harm.

Throughout the world, half of all children go to bed hungry each night and one in seven of God's children is facing starvation. Before such statistics, believers should never forget Dostoevsky's assertion that the suffering of children is the greatest proof against the existence of God; for without justice, there is no God.
It is true that you can't prove a negative.
However, the existence of God is provable in the same way a building is positive proof that there was a builder.
Reason excludes faith, Alessandro responded, watching the blood-red mite as it made a dash for the rim. It's deliberately limited. It won't function with the materials of religion. You can come close to proving the existence of God by reason, but you can't do it absolutely. That's because you can't do anything absolutely by reason. That's because reason depends on postulates. Postulates defy proof and yet they are essential to reason. God is a postulate. I don't think God is interested in the verification of His existence, and, therefore, neither am I. Anyway, I have professional reasons to believe. Nature and art pivot faithfully around God. Even dogs know that.

Consciousness of myself, combined with complete ignorance of everything that does not fall within my sphere of thinking, is the most telling proof of my substantiality outside God, of my original existence.
It was an important part of Mendelssohn's philosophical and religious view that the traditional rationalist proofs for God's existence should be sound an convincing. Kant thought they were not. So Kant's critique was world-shaking for Mendelssohn.
You don’t have to say that nature is aware of your existence, that God knows you are here. The camera gives you proof that you have lived at least once.

A prevalent fallacy is the assumption that a proof of an afterlife would also be a proof of the existence of a deity. This is far from being the case. If, as I hold, there is no good reason to believe that a god either created or presides over this world, there is equally no good reason to believe that a god created or presides over the next world, on the unlikely supposition that such a thing exists.
That God has managed to survive the inanities of the religions that do Him homage is truly a miraculous proof of His existence.
You will see the mercy of God toward His creatures, how He has provided that which is required, in proper proportions, and treated all individual beings of the same species with perfect equality. ...for it is an act of great and perfect goodness that He gave us existence; and the creation of the controlling faculty in animals is a proof of His mercy towards them, as has been shown by us.
An argument frequently used by believers [is] to force unbelievers to soften their terms by accepting their opponents' definition; "Atheist" means without a concept of God that is logically convincing, not with proof that God does not exist.
Here is the cosmological proof of the existence of God - the design argument of Paley - updated and refurbished. The fine tuning of the universe provides prima facie evidence of deistic design. Take your choice: blind chance that requires multitudes of universes or design that requires only one.... Many scientists, when they admit their views, incline toward the teleological or design argument.
