What her tender infant may grow up to be

(J. C. Ryle)

"Every inclination of his heart is evil from childhood."
    Genesis 8:21

"Surely I was sinful at birth, sinful from the time
 my mother conceived me." Psalm 51:5

Remember that 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—all is 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.
