Context

“"It is not in man that walketh to direct his steps." Of all acts, is not, for a man, repentance the most divine? The deadliest sin, I say, were that same supercilious consciousness of no sin;—that is death; the heart so conscious is divorced from sincerity, humility and fact; is dead: it is "pure" as dead dry sand is pure. David's life and history, as written for us in those Psalms of his, I consider to be the truest emblem ever given of a man's moral progress and warfare here below.” source
