Islam’s Jesus is not the same as Christianity’s Jesus. He was not God’s Son, never died on the cross, was never resurrected and was just a prophet in the same fashion as Moses and Abraham.
The Jesus of the Bible proclaimed himself to be both “The Son of Man” and “The Son of God”. He commanded his apostles to proclaim his death and resurrection and to teach that he was the only way to the Father.
John 14:6 Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me.”
