“He will keep the feet of his saints.” –1 Samuel 2:9
The Lord sees his poor scattered pilgrims traveling through a valley of tears, journeying through a waste howling wilderness, a path beset with baits, traps, and snares in every direction. How can they escape? Why, the Lord keeps their feet, carries them through every rough place, as a tender parent carries a little child; when about to fall, graciously lays the everlasting arms underneath them, and when tottering and stumbling, and their feet ready to slip, mercifully upholds them from falling altogether. Thus the Lord keeps the feet of his saints.
But do you think that he has not different ways for different feet? The God of creation has not made two flowers, nor two leaves upon a tree alike; and will he cause all his people to walk in precisely the same path? No; we have each our path, each our troubles, each our trials, each peculiar traps and snares laid for our feet. And the wisdom of the all-wise and only-wise God is shown by his eyes being in every place, marking the footsteps of every pilgrim, suiting his remedies to meet their individual case and necessity, appearing for them when nobody else could do them any good; watching so tenderly over them, as though the eyes of his affection were bent on one individual; and carefully noting the goings of each, as though all the powers of the Godhead were concentrated on that one person to keep him from harm.
