The relationship between Islam, Judaism, and Christianity

Both Islam and Christianity originated from Judaism having the same common idea that there was one god:  monotheistic. Though each religion had distinct perspective on their God. They all share a familiar relationship with their God and also the story on how earth was created is similar.  Though there main differences is that the christians believe the messiah has come (Jesus Christ) while the jews believe that the messiah has yet to come and the muslims believe that Jesus doesn't have the right to forgive the peoples sins only the god all knowing does.
