Charles H. Spurgeon on Psalms 91:11

One angel armed with the power and glory of God is stronger than a whole country. Earthly princes are subject to many changes and great unsurety of life and estate. The reason is, their enemies may kill their watch, and corrupt their guard. But what men or kingdoms can touch the Church's watch? what angels of gold are able to corrupt the angels of God? and then how can that perish that is committed to keepers so mighty and faithful? Secondly, the charge of us is given to those ministering spirits by parcels, not in gross and piecemeal, not in a lump: our members in a book, our hairs by tale and number. For it is upon record, and, as it were, delivered to them in writing in one Psalm, They keep all our bones, Ps 34:20; in this, they keep our very foot, putting it in security (Ps 91:12); and elsewhere our whole man and every member. And can a charge so precisely and so particularly given and taken, be neglected? Thirdly, their manner of keeping us, as it is set down in the text, cannot but promise great assurance; for, is not the little child safe while the nurse carrieth it in her arms, or beareth it in her hands? So while these nurses so bear us, can we be ill danger? but our nurses on earth may fall; these nurses, the angels, cannot. Robert Horn.
