Holiness of heart produces holiness of conduct. When the Spirit of Holiness rids man of all unholiness...a life in Christ begins. Only the power of a resurrected Christ can cleanse the unbelieving heart from sin and unrighteousness. When God's cleansing power takes place in the heart...the fruit of holiness flows through the make-up and conduct of a believer in Christ.
Rom 6:21-22...What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death. But now being made free from sin, and become servants to God, ye have your fruit unto holiness,
