For the flesh lusts against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other…
The spirit and the flesh, grace and nature, heavenly and earthly influences, are sometimes so fairly balanced, that, like a ship with wind and tide acting on her with equal power but in opposite directions, the believer makes no progress in the Divine life. He loses headway. He does not become worse, but he grows no better; and it is all he can do to hold his own. Sometimes, indeed, he loses ground, falling into old sins. Temptation comes like a roaring sea-squall, and, finding him asleep at his post, drives him backward on his course; and, further now from heaven than once he was, he has to pray: Heal my backsliding, renew me graciously, love me freely. For Thy name's sake, O Lord, pardon my iniquity, for it is great.
(T. Guthrie, D. D.)
