1. God empowered David (31-46)

God's way is not just good. It is perfect. His word is more than beneficial. It is flawless. His plan for us is beyond our imaginations and all his promises will be fulfilled. God alone is the Rock! He enabled David to be the king over Israel and in the same way he enables us to preach the gospel of Jesus to all the nations. Look at the words David uses in verses 33-37. This is how God equips his people. The Lord actively works to strengthen, make, stand, train, keep, help, and provide for his servants. The result in David's case was an overwhelming victory over his enemies. Even foreigners trembled and cowered before him.

2. A great victory (47-51)

The Lord lives! Let's rejoice with David. Praise be to my Rock! Let's also look beyond David's kingdom. Verse 51 says, "He gives his king great victories; he shows unfailing kindness to his anointed, to David and his descendants forever." This is a prophecy about the Messiah. Everything that was true of David has an even greater fulfillment in Jesus, who is the Son of David and our eternal King. He is the one whom God has avenged, freeing him from all his enemies and placing the nations under his feet. Jesus reigns in victory and unfailing kindness.
