The function of prayer is not to influence God, but rather to change the nature of the one who prays.

If anyone thinks he has faith and yet is indifferent towards this possession, is neither cold nor hot, he can be certain that he does not have faith. If anyone thinks he is Christian and yet is indifferent towards his being a Christian, then he really is not one at all. What would we think of a man who affirmed that he was in love and also that it was a matter of indifference to him?

People try to persuade us that the objections against Christianity spring from doubt. That is a complete misunderstanding.

As a result, people have hitherto been beating the air in their struggle against objections, because they have fought intellectually with doubt instead of fighting morally with rebellion.
