God is. And He is holy. Psalm 139 exposes our hearts and minds to the omniscience, omnipresence and omnipotence of God. He is all knowing. He is everywhere at all times. He is all powerful. We learn in the Scriptures that God is eternally self-existent; He is and always has been. The name, “Yahweh” occurs more than any other name of God in the Psalms. “Yahweh” captures more than any other this essential truth about the God of the Bible. God has not only created humanity in His image but has also entered into covenant relationship with His chosen people. In your English translations, Yahweh will often appear as LORD. In Psalm 139, David lays his life bare before God that any sin may be exposed and made clean in light of God’s holiness.
