You’ll need a Bible.
Ask an older child to help you with this. Have the child sit in a chair and close his or her eyes. Then snap your fingers somewhere along the imaginary arched line that would be formed if the child’s hair were cut in a mohawk. Each time you snap, ask the child to keep his or her eyes closed and point to where you snapped. (The intriguing thing is that the child will get it wrong about 50 percent of the time.) Have the child open his eyes as you tell how he did.
Say: In a moment, you’ll each find a partner. One of you will sit on a chair and have your partner snap over your head, like I did. Now here’s the thing you want to watch for. The experiment is much more interesting if you keep your snaps in a line that’s like a mohawk. So in other words, picture a line running down the person’s head (demonstrate). You don’t want a snap that’s closer to the left or right ear. Keep it within an arch going right straight over their head and back. Listen very carefully because there will be a lot of snaps in this room. So spread out.
Then form pairs and have partners do the same thing, trading so each one gets to do both roles.
Afterward ask: How easy or difficult was it to figure out where the snapping was coming from?
Read aloud Romans 12:1-2.
Ask: How easy or difficult is it to know what God wants you to do? What do these verses say we can do so we know for sure where God is leading us?
