True wisdom, wrote John Calvin, consists of two parts: the knowledge of God and the knowledge of ourselves. With an eloquence which is itself awe-inspiring, Psalm 139 shows us how such true wisdom is discovered. Its magnificent statement of the glorious majesty, omniscience, and omnipresence of God combines with its profound and penetrating descriptions of the experiences of the children of God. In this small volume, these biblical truths are given clear and satisfying exposition in the hands of one of the great modern masters of the Old Testament.
