What does Psalm 25:10 mean?

The Lord's way of dealing with those who humbly obey Him is characterized by never-ending care and faithfulness. David had witnessed the Lord's love and faithfulness in his own life. The Lord had protected him countless times when David faced imminent danger. Even when he was a shepherd boy, David had experienced the Lord's protection from a bear and a lion (1 Samuel 17:34–35). Later, in love and faithfulness, the Lord had given David a decisive victory over Goliath (1 Samuel 17:49–51). He had also given him victory over the Philistines (1 Samuel 23:5) and kept him safe when Saul tried to kill him (1 Samuel 18:11).

In the midst of Lamentations, the writer observes: "The steadfast love of the LORD never ceases; his mercies never come to an end; they are new every morning; great is your faithfulness" (Lamentations 3:22–23). Believers can never exhaust the Lord's love and faithfulness because He will never leave us or forsake us (Hebrews 13:5–6).
