No more soul-destroying doctrine could well be devised than the doctrine that sinners can regenerate themselves, and repent and believe just when they please. As it is a truth both of Scripture and of experience that the unrenewed man can do nothing of himself to secure his salvation, it is essential that he should be brought to practical conviction of that truth. When thus convinced, and not before, he seeks help from the only source whence it can be obtained.
