Lest Satan should get an advantage of us. — Literally, lest we should be cheated (or out-maneuvered) by Satan. The phraseology is that of one who is, as it were, playing a game against the Tempter, in which the souls of men are at once the counters and the stake. The Apostle’s last move in that game had been to “give the sinner over to Satan” with a view to his ultimate deliverance. But what if Satan should outwit him, by tempting the sinner to despair or recklessness? To guard against that danger required, as it were, another move. Stratagem must be met by strategy. The man must be absolved that he may be able to resist the Tempter.
We are not ignorant of his devices. — The language comes from a wide and varied experience. St. Paul had been buffeted by a messenger of Satan (2 Corinthians 12:7); had once and again been hindered by him in his work (1 Thessalonians 2:18); was ever wrestling, not with flesh and blood, but with principalities and powers (Ephesians 6:12); and so he knew how the Tempter could turn even the rules of an ascetic rigour, or the remorse of a sin-burdened conscience, into an occasion of yet further and more irremediable sin.
