It is the Lord's kindness that he will take the scum off us in the fire. Who knows how needful winnowing is to us, and what dross we must want ere we enter into the kingdom of God? So narrow is the entry to heave, that our knots, our bunches and lumps of pride, and self-love, and idol-love, and world-love must be hammered off us, that we may throng in, stooping low, and creeping through that narrow and thorny entry.
