What does the Bible say about David's reliance on God?

The narrative of David in 1 Samuel demonstrates his journey of reliance on God amidst trials. Initially, David leaned on his own understanding, attempting to save himself from Saul's threats. This self-reliance led to disastrous consequences, including the death of many priests. However, as David found himself in the cave of Adullam, he was brought to a humbling realization of his dependency on God alone. In Psalm 57 and Psalm 142, he cries out for mercy and recognizes his utter helplessness, acknowledging that God knows his path. The transformative experience in the cave leads David to a renewed faith, where he learns to wait on the Lord, trust in His mercy, and seek God's will through prayer.
