When you are at work, you represent your employer. When you are with friends, you represent your family. When you are at an athletic event, you represent your school or team. When you pronounce that you are a Christian, you represent Christ!
Right or wrong, people tend to judge everyone in the group that you represent by your actions. Be an excellent representative!
Colossians 3:17 (NLT) - “And whatever you do or say, do it as a representative of the Lord Jesus, giving thanks through him to God the Father.”
