“Why art thou cast down, O my soul? and why art thou disquieted within me? hope thou in God; for I shall yet praise him, who is the health of my countenance, and my God.” Psalm 42:11
Moreover we see that a godly man can cast a restraint upon himself, as David here stays himself in falling. There is a principle of grace, that stops the heart, and pulls in the reins again when the affections are loose. A carnal man, when he begins to be cast down, sinks lower and lower, until he sinks into despair, as lead sinks into the bottom of the sea.
