Proverbs 27:2
Let another praise you, and not your own mouth;
a stranger, and not your own lips.
"It's about you!" is a phrase often heard. For Christians, especially, our goal is to give God all the glory. Our Lord tells us, "Let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven" (Matthew 5:16). And the apostle Paul writes, "Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things" (Philippians 4:8). He then continues with, "What you have learned and received and heard and seen in me—practice these things, and the God of peace will be with you" (Philippians 4:9).
Commending ourselves is evidence of pride. We must do that which is commendable, for which even strangers may praise us. But as we do good works that may be seen, we must not do them with the purpose that they be seen.
