Islam is from the devil. There I said it!
John said it first: "By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already." (I John 4:2-3 ESV)
Agreed. Allah is an impersonal singularity knowable only to mystical Imam, meaning Islam is only peaceful if Imams say it is. So what does a nature worship system have to do with Jesus Christ and His Church?
