The short answer is that “glorification” is God’s final removal of sin from the life of the saints (i.e., everyone who is saved) in the eternal state (Romans 8:18; 2 Corinthians 4:17). At Christ’s coming, the glory of God (Romans 5:2)—His honor, praise, majesty, and holiness—will be realized in us; instead of being mortals burdened with sin nature, we will be changed into holy immortals with direct and unhindered access to God’s presence, and we will enjoy holy communion with Him throughout eternity. In considering glorification, we should focus on Christ, for He is every Christian’s “blessed hope”; also, we may consider final glorification as the culmination of sanctification.
Final glorification must await the manifestation of the glory of our great God and Savior Jesus Christ (Titus 2:13; 1 Timothy 6:14). Until He returns, we are burdened with sin, and our spiritual vision is distorted because of the curse. “For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known” (1 Corinthians 13:12). Every day, we should be diligent by the Spirit to put to death what is “fleshly” (sinful) in us (Romans 8:13).
