As one of the mighty messengers of Allah.(God)
The second last in the line of prophets from Adam till Muhammad.
He never died on the cross. He was raised up alive.
He is alive up in the heavens, waiting for his second come back to fight off the anti Christ (Dajjal), and to put an end to all idol worhip, atheism, agnostism, and all other isms, and mythologies, and bring back peace and unity by reinforcing his original teachings, the Worship of One God, Islam.
We see him as a Prophet, a human being just like you or me. We believe his mother was the Virgin Mary, and he had no father. We believe that God has no kin.
