What is sanctification?

Sanctification is a work of God’s grace, whereby they whom God hath, before the foundation of the world, chosen to be holy, are in time, through the powerful operation of his Spirit ^[1] applying the death and resurrection of Christ unto them,^[2] renewed in their whole man after the image of God;^[3] having the seeds of repentance unto life, and all other saving graces, put into their hearts,^[4] and those graces so stirred up, increased, and strengthened,^[5] as that they more and more die unto sin, and rise unto newness of life.^[6]
