2 Corinthians 7:1

These verses contain a double exhortation: - I. To make a progress in holiness, or to perfect holiness in the fear of God, Co2 7:1. This exhortation is given with most tender affection to those who were dearly beloved, and enforced by strong arguments, even the consideration of those exceedingly great and precious promises which were mentioned in the former chapter, and which the Corinthians had an interest in and a title to. The promises of God are strong inducements to sanctification, in both the branches thereof; namely, 1. The dying unto sin, or mortifying our lusts and corruptions: we must cleanse ourselves from all filthiness of flesh and spirit. Sin is filthiness, and there are defilements of body and mind. There are sins of the flesh, that are committed with the body, and sins of the spirit, spiritual wickednesses; and we must cleanse ourselves from the filthiness of both, for God is to be glorified both with body and soul. 2. The living unto righteousness and holiness. If we hope God is our Father, we must endeavour to be partakers of his holiness, to be holy as he is holy, and perfect as our Father in heaven is perfect.
