If justification can be explained only by the sovereign grace of God, then sanctification can be rooted only in the same cause. God’s sovereign grace stabilizes the Christian life. Newton explains, “That I am still preserved in the way, in defiance of all that has arisen from within and from without to turn me aside, must be wholly ascribed to the same sovereignty,” that is, the same sovereignty that saved him.
