They all believe that they are important...
Christians: They believe that Jesus is the son of God
Judaism: They have Many Prophets. They Believe that to be a prophet you must have been chosen by God to talk to people, and they take them as role models.
Islam: They thing the same thing as Judaism. They believe that there were many prophets and Messengers. Their Main Prophet is Muhammad (S), they take him as a role model. They believe he is the last messenger.
