Charles H. Spurgeon on Psalms 18:29

"For by thee have I run through a troop; and by my God have I leaped over a wall." Whether we meet the foe in the open field or leap upon them while they lurk behind the battlements of a city, we shall by God's grace defeat them in either case; if they hem us in with living legions, or environ us with stone walls, we shall with equal certainty obtain our liberty. Such feats we have already performed, hewing our way at a run through hosts of difficulties, and scaling impossibilities at a leap. God's warriors may expect to have a taste of every form of fighting, and must by the power of faith determine to quit themselves like men; but it behoves them to be very careful to lay all their laurels at Jehovah's feet, each one of them saying, "by my God" have I wrought this valiant deed. Our spolia optima, the trophies of our conflicts, we hereby dedicate to the God of Battles, and ascribe to him all glory and strength.
