David closed this long psalm of triumph and victory with a doxology. "The Lord lives! Blessed by my Rock! Let the God of my salvation be exalted" (v. 46). David had been a fugitive. He had been waiting for the day when he could ascend the throne. Now the day had come. How did he respond? He glorified God.
I suppose some of us would have said, "Well, my enemies are gone. Now I can do what I please. My battles are over. I've been put into a large place. Therefore, watch out, everybody, here I come!" But David didn't have that attitude at all. He gave glory to God, He ended his song with a hymn of praise to the One who had delivered him. "Therefore I will give thanks to You, O Lord, among the Gentiles, and sing praises to Your Name" (v. 49). Here was David, a Jew, saying, "I want these Gentiles to know how great my God is." Are you concerned about letting the nations know how great my God is." Are you burdened to tell the gospel to other people? If the Lord has saved you and delivered you, then you should be telling others what He has done for you.
David closed his song of victory by blessing the Lord. "The Lord lives!" (v. 46). Isn't it good to know that we trust in the living God? Some people may worship a dead god, but we don't. We are the children of the living God. David said, "God is alive, and He is my rock and my salvation. I want Him to be exalted." And he concluded, "Great deliverance He gives to His king" (v. 50).
How do you respond after a victory? So often Christians fail to exalt the Lord. You trust in a living God, who protects you and delivers you. He deserves your worship and praise. Have you given God the glory for your victories?
