What does the Bible say about God's knowledge of our sins?

According to Psalm 90:8, the psalmist reveals that our iniquities are set before God, and our secret sins are exposed in the light of His presence. This underscores the omniscience of God; He sees all actions and thoughts, rendering every hidden sin fully transparent before Him. In this reality, we can understand that there is no place we can hide from the gaze of our Creator. Moses, the author of this psalm, was acutely aware of God's holiness and justice, as well as His merciful provision for redemption. Therefore, this truth about God's knowledge serves not only as a warning but also a call to humble ourselves before Him, recognizing our need for His grace and forgiveness.
