"The question I want you to consider is simply this: Which is more important, the birth or the training? I suggested what training can do and what it cannot do. And so the matter comes down to this: the nature we have is the one we were born with. Training can go so far, but birth, especially the new birth, establishes the true nature. And this is the difference between what I will call “denominational churchianity” and true Christianity. We are training people every week to be good church people. But when left to themselves, they will revert to their real nature and act like themselves. They have been trained to act like a good Christian on Sunday, but it is only an act. The rest of the week they act like themselves, naturally."
