If Muhammad is God’s final prophet, then he MUST be predicted in the Bible (7:157; 61:6). In this post I will deal with the Comforter in John 14:

I will ask the Father, and he will give you another Comforter, to be with you forever, even the Spirit of truth … The Comforter, the holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you. (14:16-17, 26)

I will give five reasons why this Comforter can’t refer to Muhammad:

1) Jesus didn’t mention anything of a ‘final prophet’ in John 14. In reality, anyone can be a comforter, including a coach, a doctor or a teacher. So when Muslims say that he was foretelling the coming of Muhammad as God’s final prophet, they read much more into the text than what it actually says.  

2) Earlier in the same gospel, Jesus said that ”salvation is from the Jews” (4:22), which means that salvation is not from the Arabs. So why would Jesus refer to the Arab guy Muhammad in John 14? The truth is that he didn’t.

3) Jesus called the Comforter the SPIRIT of truth. Was Muhammad a spirit? No, he was a human being like the rest of us. In surah 18:110, Allah tells Muhammad; ”Say, ‘I am only a human like you.'” This means he could not have been this Comforter. 

4) By saying ”the Comforter, the holy Spirit” (14:26), Jesus showed that these two titles are synonymous, i.e. the Comforter is the same as the holy Spirit (and the Spirit of truth). 

5) Jesus promised his disciples that the Comforter would ”bring to your (the disciples) remembrance all that I said to you”. How could Muhammad have fulfilled this when he was born 600 years later and more than 700 miles from Jerusalem? He couldn’t!  

Then raises the question: when was Jesus’ promise of the Comforter fulfilled? It was fulfilled in Jerusalem (not Mecca) a few weeks after his death and resurrection:

When the day of Pentecost arrived, they (the disciples) were all together in one place. And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. And divided tongues as of fire appeared to them and rested on each one of them. And they were all filled with THE HOLY SPIRIT and began to speak in other tongues as THE SPIRIT gave them utterance. (Acts 2:1-4)

Jesus had promised his disciples that the Comforter would be with them forever. And now, from this day onwards, it became a reality. Muhammad could impossibly have fulfilled this. In sum: John 14 is a prediction of the holy Spirit dwelling in Jesus’ disciples, and has nothing to do with a guy living in Saudi Arabia 600 years later.
