Not sure why you are jumping from John 14:16, then to John 15:26 and back to John 14:26…???
Since you posted John 14.26, read it carefully.
Jesus said the Comforter is the Holy Spirit whom God will send in Jesus name
The Holy Spirit will teach you things and help you remember everything I’ve preached
Mohammad did not “preach” anything which Jesus stated in the Gospels.
I also want to address 14.16 which you posted above - however, you didn’t post the whole thing. But I guess that’s what you get from the bogus anti Christian site answering Christianity…
14.16
“**I will ask the Father, and He will give you another Helper, that He may be with you forever;
17that is the Spirit of truth, whom the world cannot receive, because it does not see Him or know Him, but you know Him because He abides with you and will be in you**.
Are you claiming since you believe the Comforter is Muhammad is also the Holy Spirit & The Spirit of Truth with Jesus Apostles…???
And the above passage also states “world cannot receive because it does NOT see HIM or know HIM.”
Is Mohammad invisible…??? Is he a spirit…???
Christ is clear with His message - He is not speaking of Mohammad.
