This is for some1 with a CREATIVE mind?

-I am a youth minister and this friday i will be teaching a message called "keys of the kingdom." its about getting into heaven and how to get others into heaven. but my main goal is not to teach instead i need to get these kids on fire for GOD. i need some sort of game or activity (approx. 5-15 minutes) to relate to the message so that they will still enjoy themselves. please give me a detailed answer
