2 Corinthians 10:7

Look at what is before your eyes . If anyone is confident that he is Christ’s , let him remind himself that just as he is Christ’s , so also are we .

You are judging by appearances. If anyone is confident that they belong to Christ, they should consider again that we belong to Christ just as much as they do.

Do ye look on things after the outward appearance? If any man trust to himself that he is Christ's, let him of himself think this again, that, as he is Christ's, even so are we Christ's.
