Yeah the post is valid, but not as a reference to Muhammad being the last of all prophets.
What I pointed out was the illogical description of the Koran to the account of the cross.
It also seems illogical that Jesus should still be alive and return, while the greatest of all prophets remains dead in a grave.
That Jesus should be a follower of Islam is also illogical, as the Injeel you and every Muslim is told to believe in clearly states, that He is the Way; he does not follow anyone path.
But could you please explain the reason for Jesus' secret escape to heaven, and why Allah himself created the lie that Jesus Christ died.
And Why the earliest Christians which the Qur'an refers to as victorious did not believe in the view that Jesus did not die but was substituted by another.
If these Christians got it wrong, why does the Qur'an refer to them as victorious.
