Gospel Standard Article XIX We believe in the sanctification of God's people, the term sanctification signifying a separation and setting apart by and for God. This, in the child of God, is three-fold: i, by election by God the Father
(Jude I); ii, by redemption by God the Son
(John 17:19); and iii, by the almighty regenerating operation of God the Holy Ghost
(Rom. 15:16.) We believe that the blessed Spirit is the Author of what is styled in Scripture the new creature, or creation
(2 Cor. 5:17, Eph. 4:24), or new heart
(Ezek. 36:26); being, in truth, an implantation of the Divine nature
(2 Pet. 1:4), through which the child of God would, according to the inner man
(Rom. 7:22), be holy as God is holy, and perfectly fulfil all the good pleasure of the Father's will; but groans being burdened, being constantly opposed by the contrary workings of the old man.
(Rom. 7, Gal. 5:17.) We reject the doctrine of progressive sanctification, or that a child of God experiences such a gradual weakening, subduing, or rectification of the old nature, called in Scripture the old man
(Eph. 4:22, Col. 3:9), or such a continued general improvement
as shall make him at any time less dependent upon the communications of the Spirit and grace of Christ for all goodness, or less a poor, vile, wretched, helpless sinner in himself, and in his own estimation.
(John 15
art of 5, 2 Cor. 3:5, Rev. 3:17.)
