7. That you are not [consciously] falling behind or lacking in any special spiritual endowment or Christian grace [the reception of which is due to the power of divine grace operating in your souls by the Holy Spirit], while you wait and watch [constantly living in hope] for the coming of our Lord Jesus Christ and [His] being made visible to all.
8. And He will establish you to the end [keep you steadfast, give you strength, and guarantee your vindication; He will be your warrant against all accusation or indictment so that you will be] guiltless and irreproachable in the day of our Lord Jesus Christ (the Messiah).
