I believe in reincarnation, so do I need Christianity?

I don't know what you mean by "needing" Christianity. I think that I might believe in reincarnation as well. I'm not sure yet if I do. I think as far as religions go, that this is a Hindu belief, however, I think it's possible (maybe not "right" as far as religions go) to believe in Jesus as being the son of God, AND in believing in Reincarnation.
