6 In my distress I called upon the Lord; to my God I cried for help. From his temple he heard my voice, and my cry to him reached his ears. 7 Then the earth reeled and rocked; the foundations also of the mountains trembled and quaked, because he was angry. 8 Smoke went up from his nostrils, and devouring fire from his mouth; glowing coals flamed forth from him. 9 He bowed the heavens, and came down; thick darkness was under his feet. 10 He rode on a cherub, and flew; he came swiftly upon the wings of the wind. 11 He made darkness his covering around him, his canopy thick clouds dark with water. 12 Out of the brightness before him there broke through his clouds hailstones and coals of fire. 13 The Lord also thundered in the heavens, and the Most High uttered his voice, hailstones and coals of fire. 14 And he sent out his arrows, and scattered them; he flashed forth lightnings, and routed them. 15 Then the channels of the sea were seen, and the foundations of the world were laid bare, at thy rebuke, O Lord, at the blast of the breath of thy nostrils. 16 He reached from on high, he took me, he drew me out of many waters. 17 He delivered me from my strong enemy, and from those who hated me; for they were too mighty for me. 18 They came upon me in the day of my calamity; but the Lord was my stay. 19 He brought me forth into a broad place; he delivered me, because he delighted in me.

Commentary on Psalm 18:1-19
(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.
