Charles H. Spurgeon on Psalms 18:33

The conqueror's feet had been shod by a divine hand, and the next note must, therefore, refer to them. "He maketh my feet like hinds' feet, and setteth me upon my high places." Pursuing his foes the warrior had been swift of foot as a young roe, but, instead of taking pleasure in the legs of a man, he ascribes the boon of swiftness to the Lord alone. When our thoughts are nimble, and our spirits rapid, like the chariots of Amminadib, let us not forget that our best Beloved's hand has given us the choice favour. Climbing into impregnable fortresses, David had been preserved from slipping, and made to stand where scarce the wild goat can find a footing; herein was preserving mercy manifested. We, too, have had our high places of honour, service, temptation, and danger, but hitherto we have been kept from falling. Bring hither the harp, and let us emulate the psalmist's joyful thanksgiving; had we fallen, our wailings must have been terrible; since we have stood, let our gratitude be fervent.
