What limits it from without can not be
answered any more satisfactorily than the Hindu philosopher's postulation of an elephant
standing upon a turtle
standing upon a serpent, etc, to explain why the universe maintains its position in space.
The
answer must undoubtedly be that Jesus himself had brought home to the hearts of those who really heard his words that God
stood ready to receive not simply the righteous — there was none righteous — but the penitent, those who acknowledged the absolute righteousness of God, felt the awful force of its demands
upon them, realized how far short they fell of it, and with humble and contrite hearts sought his forgiveness and help.
