Muslim Jesus Vs Biblical Jesus

8. Islamic Jesus was never crucified and therefore was not resurrected

And because of their saying (in boast), ‘We killed Messiah ‘Eesa (Jesus), son of Maryam (Mary), the Messenger of Allah,’ — but they killed him not, nor crucified him, but it appeared so to them the resemblance of ‘Eesa (Jesus) was put over another man (and they killed that man)], and those who differ therein are full of doubts. They have no (certain) knowledge, they follow nothing but conjecture. For surely; they killed him not [i.e. ‘Eesa (Jesus), son of Maryam (Mary)]: But Allah raised him [‘Eesa (Jesus)] up (with his body and soul) unto Himself (and he is in the heavens). And Allah is Ever All Powerful, All Wise [al-Nisaa’ 4:157-158]
vs.
Biblical Jesus which (by his death and resurrection) saved his people from their sins

Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live: John 11;25

And if Christ be not risen, then [is] our preaching vain, and your faith [is] also vain.

I Corinthians 15:14
