The jeweller who finds the pearl of great price clears everything from his display shelf, apart from a little black box of little value. The box is permitted on the shelf because it does not attract or distract. Actually, as a background, it enhances the pearl of great price. The pearl is put in the little black box. That is what 2 Corinthians 4:7 declares, “We have this treasure in earthen vessels, (Why?) that the excellency of the power be of God, and NOT of us.”
