You'll have to tell me then how Christianity is taught.
The Apostle Paul told the church that if it were not for His resurrection from the dead, we worship in vain.
What makes Christianity different from ALL religions is that the God-man was resurrected from the dead.
In Romans 9, Paul tells us that "If we confess with our mouths the Lord Jesus, and believe in our hearts that God has raised Him from the dead, we will be saved."
That is the Christian message. If the Koran does not teach that truth 100%, along with the verse that says He is the onl Way to God, it does not teach Christianity.
The mere mention of Jesus or Christian principles does not equate to teaching Christianity, especially when it is short the death scene and its subsequent resurrection.
In Romans 9, Paul tells us that "If we confess with our mouths the Lord Jesus, and believe in our hearts that God has raised Him from the dead, we will be saved."Sure, then I'll confess with my mouth and believe in my heart that God has raised Him from the dead, and then just sin away coz I'll be saved anyway. That's what I always found to be ridiculous about Saul, err, Paul. Then again, all he needed to do was to convince a bunch of simpletons.
That is the Christian message.
