Hunted and chased like an animal, David had been in terrible distress and danger, but God had preserved his life and rescued him. Because of God's help, David hadn't just survived; he had emerged victorious. So he sings Psalm 18, a psalm of thanksgiving for all God has done and for who he is to David. It is a great song of worship and praise for the Lord's diving intervention in delivering David against all odds from his enemy Saul and for bringing David through his difficulties to a future and hope.
In singing God's praises, David uses vivid metaphors: "my rock" (stability and security), "my shield" (the one who guards and keeps me safe), "the strength of my salvation", (my source of strength when I'm weak), and "my stronghold", (the place I go for protection). In David's darkest hour the Lord revealed himself in these ways, and He wants to reveal himself in our lives too- right where we are in our victories. Ask Him to reveal himself in whatever you're facing today, and join David in praising the Lord who is truly "worthy of praise"!
Lord, when I am overwhelmed with difficulties, be my rock- my source of security in an uncertain world. In you along I find protection. You are my stronghold; I need nothing else. Be my strength when I am weak. By my shield of protection.
