It would be incredible to start giving each other God-honoring nicknames. When something significant happened in the life of an individual in the Bible, God often marked that event by changing the name of that person, like Saul into Paul, Simon to Peter, and Jacob to Israel. Imagine nicknames that would describe one's gifts and talents. You can get creative with it. Maybe nicknames like the Rock (for someone with strong faith), T-Dog (for someone with Truth) or the Easy-E (for a person who is an Encourager). Every time you call your friends by their nicknames you are building them up. Remember, name calling is usually bad, but in this case, name-call as much as you want!
Extra Reading: 2 Kings 5:1-15
"Lord Jesus, I realize that names are powerful. Reveal to me God-honoring names for my friends. Help me to build others up. Let me speak life into them, even through a nickname. I desire as a competitor to be known for my faith not my success. May my love and commitment to You be the way people define me. Amen."
