Charles H. Spurgeon on Psalms 18:1

God hath, as it were, made himself over to believers. David doth not say, God will give me or bestow salvation upon me; but he saith, "He is the horn of my salvation." It is God himself who is the salvation and the portion of his people. They would not care much for salvation if God were not their salvation. It more pleaseth the saints that they enjoy God, than that they enjoy salvation. False and carnal spirits will express a great deal of desire after salvation, for they like salvation, heaven, and glory well; but they never express any longing desire after God and Jesus Christ. They love salvation, but they care not for a Saviour. Now that which faith pitcheth most upon is God himself; he shall be my salvation, let me have him, and that is salvation enough; he is my life, he is my comfort, he is my riches, he is my honour, and he is my all. Thus David's heart acted immediately upon God, "I will love thee, O Lord, my strength. The Lord is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower." It pleased holy David more that God was his strength, than that God gave him strength; that God was his deliverer, than that he was delivered; that God was his fortress, his buckler, his horn, his high tower, than that he gave him the effect of all these. It pleased David, and it pleases all the saints more that God is their salvation, whether temporal or eternal, than that he saves them: the saints look more at God than at all that is God's. —Joseph Caryl.
