funandsmart: Well, Christianity says that Jesus will return, that he will fully inaugerate his Kingdom, and that there will be a new heaven and a new earth that are created.
there is a lot of discussion on the specific details of what whill happen. Some see there being Christ returning and starting up a 1000 year reign of peace and prosperity. Others see the reign as being less geopolitical and happening before Jesus return, others don't believe in a literal millenium but Jesus returning none the less.
My understanding, with which, Muslims are likely to disagree - so no disprect intended here. My understanding is that the Koran was put together by Mohommad from a mixture of the teachings of Jewsh traders that he dealt with. Apart from that I do not have any knowledge about the 12th Imam Mehdi
Well,Actaully Quran is the book of God,words of God not taken from any person,Gabriel Brought the Messages to the Holy Prophet for the peoples,And 12 imam Mehdi is Grandson of Holy prophet and will return wth jesus Christ
Also Quran approve the Bible
