1 Cor 6:9

6:9 the unrighteous will not inherit the kingdom of God. See “Antinomianism” at 1 John 3:7. That the things of this world are incompatible with the kingdom of God is a recurring principle in Scripture (15:50; Gal. 5:21). The question arises whether anyone at all can be saved, since all are wicked. Paul’s answer is twofold: on the one hand, God delights in justifying the wicked (Rom. 4:5); on the other hand, those whom God justifies (declares righteous because of Christ’s death) He also sanctifies (leads into a holy way of life; Rom. 6:1–4). Paul is confident that the Corinthians are true believers, justified and sanctified (v. 11 note), and that their present misbehavior is an anomaly that can be corrected. But it must be corrected. Persistence in wickedness would be an indication that their faith is false and that they have no place in the kingdom.
