Few Psalms have such strikingly powerful declarations of aspects of God's nature, God's attributes. David did not come to know God's attributes through some dusty book of theology. Here in Psalm 139, David is arrested in full flight from God by deeply personal revelations of the Omniscient God, the Omnipresent God, the Omnipotent Creator God, the Ruling God and the Shepherd God. David sees God's very nature and is transformed. And by God's mercies, so shall we be as we study Psalm 139 together.
