'Appearances' in the Bible

We are not commending ourselves to you again, but are giving you an occasion to be [rightfully] proud of us, so that you will have an answer for those who take pride in [outward] appearances [the virtues they pretend to have] rather than what is [actually] in heart.

You are looking at outward appearances. If anyone is confident that he belongs to Christ, he should reflect on this again: Just as he himself belongs to Christ, so too do we.
