David's life has much to teach us. In both his successes and failures, he shows in powerful ways what can happen when God is solidly at the center of your lives and what happens when God is not. David's life is a powerful challenge to young men and women – and to us all – to keep God at the center of your life wherever you go and whatever you do!
We will never outgrow our need for God. We will never outgrow our need for his grace and mercy. It is the Lord who brings the victory in our lives; he is the hero of our every success.
David's life and his psalm in 2 Samuel 22 remind us that the Christian life is warfare. Unlike David, however, no person or tribe or country is our enemy; this world so filled with temptations, our sinful hearts, and the devil—these are our enemies. But David also reminds us that ultimately, the battle is the Lord's. We don't fight alone. The Lord of the universe, the King of creation, the God who is Father, Son, and Holy Spirit is with us and in us, in front of us, behind us, above us, and below us. He is our strength and our shield, our fortress and our deliverer!
In Christ, God forgives all of our sin, but he does not remove all of the consequences. This too is part of God's mercy, that we might take responsibility for our sin, learn from the consequences, and be changed.
This passage reminds us it is the Lord who establishes his King and his kingdom Zion, where God uniquely met with his people and will dwell with them again in glory. Jesus is that King, the great high Priest and the sacrifice that allows us to draw near to God now and forever!
