- a set of wind chimes
Show the wind chimes, make them sound, and ask the young men what purpose they have. Ask if they do anything else beside make sound.
Then, read the scripture. 1 Corinthians 13:1-2 "Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing."
