Occasionally, we speak of other religions in youth group. While it used to be quite uncommon to know of anyone who was not Jewish or Christian, nowadays that is not the case. We are often surrounded by people of differing faiths, or even no faith at all. In order to fulfill the Great Commission, and to share our faith with others, it is simply logical to know some common ground from which to speak. The following link can perhaps be of use in this regard, and if nothing else is an interesting read to see how the other religions of the world "deal with" Jesus.
In Matthew 16:13-18, Jesus asks his disciples who the people say he is. Further, he asks his dearest followers who they say he is. It would likely be good to ask our friends and acquaintances the same question; it would certainly do our children well.
