Emphasise the power of God
Muslims say that Allah is so great that He wouldn’t have allowed his prophet to die. Address this by asking them which of the following would be a greater act by God:
a) To deceive people and snatch Jesus up without letting Him die.
b) To let Jesus die and then raise Him from the dead?
Raising someone from the dead is certainly the greater act. Christians proclaim, ‘God showed His awesome power by raising Jesus from the dead.’
Point to the faith of the eyewitnesses
Let us return to the scene of the cross and question the eyewitnesses:
– The centurion in charge of Jesus’ crucifixion later confessed faith in Him because Jesus exhibited such holiness. A sinful traitor like Judas (which some Muslims claim was the replacement) would never have left such an impression.
– The gospels record seven statements that Jesus made while on the cross. No one else could have said such remarkable words. For example, how could anyone other than Jesus pray for God to forgive His persecutors while in excruciating pain?
– The criminal executed alongside Jesus would not have called on Him for salvation, nor would he have received salvation, if Jesus had been just another sinner on a cross.
If possible, I would end by emphasising how the Muslim’s claim questions the trustworthiness of God. Would God promise for centuries that the Messiah would come to die for our sins, and then, at the last moment, when Jesus was about to die, exchange Christ for an impersonator? Does this description fit God? Not only would this make God out to be a liar, but He would have left us with no salvation from sin!
