“What our Heavenly Father wants us to do about our spiritual failures is like what our earthly father wants us to do about our earthly failures. When we fall off the horse, or the bike, or the high road to Heaven, we must simply climb on again as soon as we are aware of the fact that we have fallen off, rather than sitting there stewing in self-pity or self-hatred.”
