From a muslim to all Christians?

I belive too,but the problem is ,when we start telling the trruth about their book,,they give their different reasoning for it.............and in the second coming of jesus(pbuh) ,he is not coming for muslims,,personally I dont need him,for me and muslims religion is completed or jews or anybody,,,,,,,,,,rather he is coming for these kinds of christians who claim him to be this and that rather than just a plain warner ,a messenger.............and will justify them that he was just a messenger.
