Paul is using a question to scold those who are judging others. AT: "You are not God, and you are not allowed to judge one of his servants" (See: [[rc://en/ta/man/translate/figs-rquestion]])
This can be translated with an active verb. AT: "But the Lord will accept him because he is able to make the servant acceptable" (See: [[rc://en/ta/man/translate/figs-activepassive]])
