Psalm 139 is a psalm that’s known for what it teaches us about God. In this psalm David provides one of the clearest teachings in the Scriptures on the omniscience and omnipresence of God. Omniscience is the reality that God knows all things and omnipresence speaks to the fact that God is always present, everywhere. In this psalm David describes the full knowledge and presence of God and provides illustrations that add color and depth. But while this psalm is a go-to for understanding the nature of God, we miss the point of the psalm if we use it merely as a statement of theology. At the heart of the psalm is how David responds to these truths about God. As we see God for who He is it should impact the way we think and live. It should change the way we handle temptation and deal with loss. It should guard us from worry, keep us from fear and motivate our obedience.
