Let us also pass over this fire of lust, fearing which Paul—but fearing for us, inasmuch as by buffeting his body he had come no longer to fear for himself—says to us: “Flee fornication.” 1 Cor. vi. 18. Let us then flee it as though following us, though indeed it follows not behind us, but within our very selves. Let us then diligently take heed lest while we are fleeing from it we carry it with ourselves. For we wish for the most part to flee, but if we do not wholly cast it out of our mind, we rather take it up than forsake it.
