The practical and useful object of this sermon is to show to you that
if you have come of a Christian ancestry, then you are solemnly bound
to preserve and develop the glorious inheritance; or if you have come
of a depraved ancestry, then it is your duty to brace yourself against
the evil tendency by all prayer and Christian determination, and you
are to find out what are the family frailties, and in arming the
castle put the strongest guard at the weakest gate. With these smooth
stones from the brook I hope to strike you, not where David struck
Goliath, in the head, but where Nathan struck David, in the heart.
"Whose son art thou, thou young man?"
