The one thing a Muslim is stuck on is seeing Jesus as God, for God broke into creation to be a man and show us obedience unto the Father; not unto himself, but to the 1st Person in the Godhead, whereas Jesus is the 2nd Person who perfectly atoned for our sins which only God can do. No man could atone for my sins but the man who is also God the Son. All that is born of the flesh is flesh. Flesh can not atone. Jesus came in the likeness of flesh. That's the difference.
