Dead to sin, &c. We are then dead to sin when we neither live in sin by serving it, nor sin lives in us by reigning; in this case, how can we still live in it by yielding to its desires? St. Augustine (chap. vi. de spiritu et litera) thus explains the passage: when grace has caused us to die to sin; if we live again in it, we must be exceedingly ungrateful to grace. (Estius)
