Charles H. Spurgeon on Psalms 91:11

To keep thee in all thy ways. Their commission, large as it is, reaches no further: when you leave that, you lose your guard; but while you keep your way, angels, yea; the God of angels, will keep you. Do not so much fear losing your estate or your liberty or your lives, as losing your way, and leaving your way: fear that more than any tiring; nothing but sin exposes you to misery. So long as you keep your way, you shall keep other things; or if you lose any of them, you shall get what is better: though you may be sufferers for Christ, you shall not be losers by him. Samuel Sletter, (1704) in "Morning Exercises."
