Article 1. They who are united to Christ, effectually called, and regenerated, having a new heart and a new spirit created in them, are also further sanctified, really and personally, through the virtue of Christ's death and resurrection, by His Word and Spirit dwelling in them. The dominion of the whole body of sin is destroyed, and the various lusts thereof are more and more weakened and mortified and more and more quickened and strengthened in all saving graces, to the practice of all true holiness, without which no one shall see the Lord.
Article 2. This sanctification is throughout the whole man, yet imperfect in this life. There abides still some remnants of corruption in every part, whence arises a continual and irreconcilable war, the flesh lusting against the Spirit, and the Spirit against the flesh.
Article 3. In this war, the regenerate person overcomes through the continual supply of strength from the sanctifying Spirit of Christ, although the remaining corruption for a time may much prevail. The saints thus grow in grace, perfecting holiness in the fear of God.

Q. What is sanctification?
A. Sanctification is a work of God's free grace whereby we are renewed in the whole man after the image of God, and are enabled more and more to die unto sin, and live unto righteousness.
