David is the author of many of the psalms

[Mary Naeem]

David is the author of many of the psalms. In them we see the way he sought after and glorified God. He is often thought of as a shepherd king and a warrior poet. Scripture calls him “the sweet psalmist of Israel” (2 Samuel 23:1). David's life seemed filled with the range of human emotions—a common shepherd boy with great confidence in God's faithfulness who honored authorities, fled for his life, and became the king against whom all future kings of Israel would be measured. He saw many military victories. He also fell into grave sin, and his family suffered as a result. But through it all David turned to God and trusted Him. Even in the Psalms when David is downcast or despondent, we see him lift his eyes up to his Maker and give Him praise. This reliance on God and continual pursuit of relationship with God is part of what makes David a man after God's own heart.

God promised David a descendant to rule on the throne forever. That everlasting king is Jesus, the Messiah and Son of David
