181 To the chief Musician. [A Psalm] of David, the servant of Jehovah, who spoke to Jehovah the words of this song in the day that Jehovah had delivered him out of the hand of all his enemies and out of the hand of Saul. And he said, I will love thee, O Jehovah, my strength. 2 Jehovah is my rock, and my fortress, and my deliverer; my God, my rock, in whom I will trust; my shield, and the horn of my salvation, my high tower. 3 I will call upon Jehovah, who is to be praised: so shall I be saved from mine enemies. 4 The bands of death encompassed me, and torrents of Belial made me afraid. 5 The bands of Sheol surrounded me, the cords of death encountered me. 6 In my distress I called upon Jehovah, and I cried out to my God; he heard my voice out of his temple, and my cry came before him, into his ears.

(Read Psalm 18:1-19)
The first words, "I will love thee, O Lord, my strength," are the scope and contents of the psalm. Those that truly love God, may triumph in him as their Rock and Refuge, and may with confidence call upon him. It is good for us to observe all the circumstances of a mercy which magnify the power of God and his goodness to us in it. David was a praying man, and God was found a prayer-hearing God. If we pray as he did, we shall speed as he did. God's manifestation of his presence is very fully described, Hebrews 5:7. God made the earth to shake and tremble, and the rocks to cleave, and brought him out, in his resurrection, because he delighted in him and in his undertaking.
