"He will not suffer thy foot to be moved." (Psalm 121:3)
If the Lord will not suffer it, neither men nor devils can do it. How greatly would they rejoice if they could give us a disgraceful fall, drive us from our position, and bury us out of memory! They could do this to their heart's content were it not for one hindrance, and only one: the Lord will not suffer it; and if He does not suffer it, we shall not suffer it.
The way of life is like traveling among the Alps. Along the mountain path one is constantly exposed to the slipping of the foot. Where the way is high the head is apt to swim, and then the feet soon slide; there are spots which are smooth as glass and others that are rough with loose stones, and in either of these a fall is hard to avoid. He who throughout life is enabled to keep himself upright and to walk without stumbling has the best of reasons for gratitude. What with pitfalls and snares, weak knees, weary feet, and subtle enemies, no child of God would stand fast for an hour were it not for the faithful love which will not suffer his foot to be moved.
Amidst a thousand snares I stand
Upheld and guarded by thy hand;
That hand unseen shall hold me still,
And lead me to thy holy hill.
