How could it occur to anyone to demonstrate that God exists unless one has already allowed Himself to ignore Him? A king's existence is demonstrated by way of subjection and submissiveness. Do you want to try and demonstrate that the king exists? Will you do so by offering a string of proofs, a series of arguments? No. If you are serious, you will demonstrate the king's existence by your submission, by the way you live. And so it is with demonstrating God's existence. It is accomplished not by proofs but by worship. Any other way is but a thinker's pious bungling.
Soren KierkegaardTo defend something is always to discredit it. Let a man have a warehouse full of gold, let him be willing to give away a ducat to every one of the poor - but let him also be stupid enough to begin this charitable undertaking of his with a defense in which he offers three good reasons in justification; and it will almost come to the point of people finding it doubtful whether indeed he is doing something good. But now for Christianity. Yes, the person who defends that has never believed in it.
Soren KierkegaardHow did I get into the world? Why was I not asked about it and why was I not informed of the rules and regulations but just thrust into the ranks as if I had been bought by a peddling shanghaier of human beings? How did I get involved in this big enterprise called actuality? Why should I be involved? Isn't it a matter of choice? And if I am compelled to be involved, where is the manager—I have something to say about this. Is there no manager? To whom shall I make my complaint?
