I've never witnessed a baby birth itself, but I've heard plenty of professing Christians convey they birthed themselves into the kingdom by casting a free will vote.
They seem to have developed this idea that somehow they just always loved God even when lost (contrary to his Word) and that they wanted to prove their love to God and came to him, denying the inability to do so expressed in Scripture. They also sought God, contrary to his word. Their ability is way over the top! When Jesus said we are unable, they proved him wrong and have a verse to prove it!
They did all this, and God wants it this way, because he wants people to come to him out of real true love for him, because then they prove they're not robots like those evil Calvinists, and did it out of their own precious sincerity. He now waits for people to come to him, he made the offer, and waits for people to exercise their innate ability.
And all this time I thought Jesus saved, not men, that he came to seek and save that which was lost, saved the ungodly, came to call sinners to repent, all being unable to save themselves or even come to him, having no love for God and actually being hostile toward him. Man, I've had it all wrong!
