The Psalms are filled with references to God being our rock and refuge. King David was not the most innocent person in the Bible: he committed adultery, was certainly guilty of envy and lust, and more or less guilty of murder. David certainly understood one thing: God was his refuge and the only path to salvation. He begged for forgiveness numerous times, realizing his sins, begging for atonement, and having faith in the Lord, his rock and refuge.
