Therefore, when a person refuses to come to Christ it is never just because of lack of evidence or because of intellectual difficulties: at root, he refuses to come because he willingly ignores and rejects the drawing of God's Spirit on his heart. No one in the final analysis really fails to become a Christian because of lack of arguments; he fails to become a Christian because he loves darkness rather than light and wants nothing to do with God.
William Lane CraigThe way in which I know Christianity is true is first and foremost is the basis of the witness of the Holy Spirit in my heart. And this gives me self-authenticating means of knowing Christianity is true wholly apart from the evidence. And therefore, even if in some historically contingent circumstances the evidence that I have available to me should turn against Christianity, I do not think that controverts the witness of the Holy Spirit.
William Lane CraigOkay, look at it this way: if the evening news has a very high probability of being accurate, then it's highly improbable that they would inaccurately report the numbers chosen in the lottery. That counterbalances any improbability in the choosing of those numbers, so you're quite rational to believe in this highly improbable event.
William Lane CraigThe point is this: If God does not exist, then life is objectively meaningless; but man cannot live consistently and happily knowing that life is meaningless; so in order to be happy he pretends life has meaning. But this is, of course, entirely inconsistent—for without God, man and the universe are without any real significance.
