Hi, I'm new here.
In the Vedas there is the concept that there is one God (the Hindus call Him Braham) but that he has many faces or avatars. He shows to each person the face he thinks that person can best relate to. So, following this way of thinking everyone may be right. God might be showing himself to Christians in the way he feels they will best perceive him; likewise with the Jews, Mormons, Buddhists, Muslims, etc.
Maybe?
Feel free to quote Bible verses but circular argument never proves a point.
