Not only is reincarnation a main concept of the eastern religions, the bible also says that Jesus was with God before he incarnated. Here are some verses that show this. John 6:38 For I came down from heaven, not to do mine own will but the will of him that sent me.and John 6:62 What if ye shall see the son of man acend up where he was before? John 17:5 And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was. So the bible too preaches the incarnation of Jesus, and if it is true for him, why not for everyone else. I get my opinions from much delving into spiritualism and occulltism, and spiritualists teach reincarnation too.
