Charles H. Spurgeon on Psalms 91:12

They, that is the angels, God's own angels, shall cheerfully become our servants. They shall bear thee up in their hands; as nurses carry little children, with careful love, so shall those glorious spirits bear up each individual believer. Lest thou dash thy foot against a stone; even minor ills they ward off. It is most desirable that we should not stumble, but as the way is rough, it is most gracious on the Lord's part to send his servants to bear us up above the loose pebbles. If we cannot have the way smoothed it answers every purpose if we have angels to bear us up in their hands. Since the greatest ills may arise out of little accidents, it shows the wisdom of the Lord that from the smaller evils we are protected.
