2 Corinthians 7:1

"Having therefore these promises, beloved." What promises? That we should be temples of God, sons and daughters, have Him indwelling, and walking in us, be His people, have Him for our God and Father. "Let us cleanse ourselves from all defilement of flesh and spirit." Let us neither touch unclean things, for this is cleansing of the flesh; nor things which defile the soul, for this is cleansing of the spirit. Yet he is not content with this only, but adds also, "Perfecting holiness in the fear of God." For not to touch the unclean thing doth not make clean, but there needeth something else besides to our becoming holy; earnestness, heedfulness, piety. And he well said, "In the fear of God." For it is possible to perfect chasteness, not in the fear of God but for vainglory. And along with this he implies yet another thing, by saying, "In the fear of God;" the manner, namely, whereafter holiness may be perfected. For if lust be even an imperious thing, still if thou occupy its territory with the fear of God, thou hast stayed its frenzy. Now by holiness here he means not chastity alone, but the freedom from every kind of sin, for he is holy that is pure. Now one will become pure, not if he be free from fornication only, but if from covetousness also, and envy, and pride, and vainglory, yea especially from vainglory which in every thing indeed it behoveth to avoid, but much more in alms-giving; since neither will it be almsgiving, if it have this distemper, but display and cruelty.
