John Wesley on 1 Corinthians 6:2

Know ye not - This expression occurs six times in this single chapter, and that with a peculiar force; for the Corinthians knew and gloried in it, but they did not practise. That the saints - After having been judged themselves. Shall judge the world - Shall be assessors with Christ in the judgment wherein he shall condemn all the wicked, as well angels as men, Matt 19:28 Rev 20:4.
