God decreed from eternity past that you would be like Christ (Rom. 8:29-30); He put His Holy Spirit in you to make sure that it would happen (Phil. 2:12-13); Christ prayed for you to be sanctified, and His prayers are always answered (Jn. 17:17); He even promises you that He will lovingly discipline you in order to return you to holiness whenever you stray (Heb. 12:5-10). How could we ever doubt that God means what He says, “Without holiness no one will see the Lord” (Heb 12:14)?
