The present work of sanctification is a work of the Holy Spirit (2 Thessalonians 2:13; 1 Peter 1:2). The goal of sanctification is to make us like Christ. This will not be accomplished until our glorification, which is called in Ephesians 4:13; 3:16-19 “the fullness of Christ.” Christ dwells in us now in measure as the “hope of glory” (Colossians 1:27) but then He will be in us as the fullness of glory (1 John 2:28-3:2). Glorification is the goal and the final stage of sanctification. At our glorification the Godhead will take full possession of our being and redemption will be complete (Romans 8:23).
There will be no “means of grace” in heaven, but an immediate enjoyment of God. When all things are subdued God will be “all in all” (1 Corinthians 15:28)—He will be all things to all the saints.
“For now through faith in Christ we are enriched, as with an earnest, with the first-fruits of the Holy Spirit. But after the Resurrection, sin being wholly taken away, the Holy Spirit will be in us, not as an earnest or in a measure; but richly bounteously and perfectly shall we enjoy the grace through Christ.”
