Do you look at things according to the outward appearance? If anyone is convinced in himself that he is Christ’s, let him again consider this in himself, that just as he is Christ’s, even so we are Christ’s. (2 Corinthians 10:7, NKJV)
Things are not always as they appear. Certainly, we must be careful of our appearance and the influence we leave on others (1 Timothy 2:9-10; 4:12). But, that is not the subject of this passage. This verse warns us not to make judgments based merely on outward appearances. When we do, we are liable to be mistaken, and even deceived (John 7:24). By doing so we have forgotten a fundamental trait of God that ought to inform our discernment: God looks at the heart instead of outward appearances (1 Samuel 16:7). Here, some Christians were trying to undermine the apostolic authority of Paul. Using carnal tactics, they complained about the strength of his epistles versus his bodily presence (2 Corinthians 10:9-10). They suggested Paul was not fully an apostle (2 Corinthians 11:5-6; 12:11-12). They compared themselves with themselves and boasted in their faithfulness (2 Corinthians 10:12, 7). On the other hand, Paul would only boast in the Lord and the work he was given to accomplish (2 Corinthians 10:13-17). Let us be careful not to use outward appearances to compare ourselves to others. Remember, “not he who commends himself is approved; but whom the Lord commends” (2 Corinthians 10:18).
