In the sea, a dolphin sights a squid. It races toward the yummy meal. But the squid sees the enemy coming. Immediately its body changes. It glows and its shape disappears. Now what the dolphin sees looks like light filtering through the water.
Then the squid squirts out inky fluid. The dolphin thinks it has found the squid again. It swims toward the dark blob.
But the squid isn't there any more. The ink cloud was only a diversion. While the dolphin tries to find the squid in the cloudy water, the squid has sped away to safety.
The squid lives in a sea full of enemies. When in danger, it changes how it looks. It blends with its surroundings. It can trick it's predators by using camouflage.
Perhaps, like the squid, it feels like there are enemies around you. Some of the kids laugh at you for going to church. You get teased because you're not allowed to watch some movies. Sometimes your friends ask you to join them in doing wrong things. It would be easy to go along - to camouflage that you are a Christian.
But don't. Camouflage is not for Christians! Jesus told us we shouldn't hide that we love God. Instead we're to let His light shine in us. We'll stand out like bright stars or a city on a hill. But our courage may light someone's way to Jesus.
