Remember children are born with a decided bias toward evil, and therefore if you let them choose for themselves, they are certain to choose wrong. The mother cannot tell what her tender infant may grow up to be – tall or short, weak or strong, wise or foolish; he may or may not be any of these it is all uncertain. But one thing the mother can say with certainty: he will have a corrupt and sinful heart. It is natural for us to do wrong… Our hearts are like the earth on which we tread; let it alone, and it is sure to bear weeds.
