For the director of music. Of David the servant of the Lord. He sang to the Lord the words of this song when the Lord delivered him from the hand of all his enemies and from the hand of Saul. He said: I love you, Lord, my strength. The Lord is my rock, my fortress and my deliverer; my God is my rock, in whom I take refuge, my shield and the horn of my salvation, my stronghold. I called to the Lord, who is worthy of praise, and I have been saved from my enemies (NIV).
The Psalms tell the story of God’s reign in song. They show God at work through his anointed king, usually David, and great David’s greater son, the Anointed One (Messiah). At times, we hear of David’s struggles, sin, sorrows, and repentance. At others, we are called to join in the celebration of God’s victories, which involve the salvation and deliverance of his people from their enemies.
In Psalm Eighteen, David celebrates how God had delivered him from the hand of all his enemies (title of the psalm). At a quick glance we might assume that this referred to the end of his life, but nearly the same words are said when he became king over all Israel, following years of struggle with his father-in-law, Saul, and other rebels against God’s choice of David as his king (2 Samuel 7:1). David is about thirty-seven at the time he wrote this. He had ruled over Judah for seven and a half years, but finally, the Lord had set him up as king over all Israel. A study of 2 Samuel 7 will show that the Lord made a covenant with David, that the Messiah would come from him. Then end of this psalm is definitely Messianic, as we will see. David’s great task became restoring the worship of the living God in Israel. To do this, he wrote many songs for public worship. Notice how the title informs us that this psalm was for the director of music. Since the Lord had brought David through many troubles to the throne, David rejoiced about God doing the same thing for Israel through the Anointed One. He glorified God, calling himself only the servant of the Lord.
Observe that David sang to the Lord the words of this song. The heart of a person set free has a song. The believer sings to the Lord. He put a new song in my mouth, a hymn of praise to our God. Many will see and fear, and they will trust in the Lord (Psalm 40:3 CSB). Thanksgiving for mercy and grace received causes those set free from sin and death to worship. Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God (Colossians 3:16 ESV).
David wanted his people to share his joy, and to prepare them to trust the Lord throughout difficult times that would certainly come. The key to all this is his love for the Lord (18:1). David was a man after God’s own heart (1 Samuel 13:14; Acts 13:22). He set his inner person on seeking the glory of the Lord. He wanted everyone to rejoice in God’s overflowing goodness, and so he gave himself to compose songs for worship for his own soul and for others to sing with him.
Are our hearts filled with songs for the Lord? Are we thankful for how he has delivered and continues to deliver us? If our songs are absent or faint, we ought to examine ourselves to find the cause of our spiritual disorder. The life of faith is meant to be a walk of thanksgiving and joy! David sought to rekindle this in his people. May our souls be filled with refreshing experiences of God’s goodness to us!
Grace and peace, David
