Muhammad (peace be upon him) was foretold 
in the Bible:

Introductory Question:  Why did GOD end His revelations with Muhammad and not with Jesus?
Answer to the question.

Question: Why do Muslims believe in Jesus' quotes from the current Bible(s) as closest to the truth?
Answer to the question.

In the Gospel of John: Muhammad is mentioned by the name and was foretold in the Gospel of John. This is a must read article!  It proves that Jesus peace be upon him predicted for the Prophet Muhammad peace be upon him to come after him.

In the Book of Isaiah: Isaiah in the Bible foretold the story of "Al-alak" that is in the Noble Quran about Muhammad.   Isaiah in the Bible foretold the story of "Al-alak" in the Noble Quran which happened to Muhammad and never happened to any other Prophet.  It is the story where the Angel Gabriel repeatedly commands the Prophet to read, and the Prophet (i.e. Muhammad) repeatedly replies "I can't read".

Isaiah's Vision: He saw Jesus riding a donkey and Muhammad riding a camel.  He also saw the destruction of Babylon (i.e. Iraq today) and its idol gods, and replacing them with a Divine Religion (i.e. Islam today).

The story of King Heraclius of the Byzantine and the foretold Prophet (Muhammad) in the Bible.  See how he was convinced that Prophet Muhammad of Arabia was indeed the foretold Prophet that Jesus predicted to come.

Muhammad is mentioned by the exact name in 
the Gospel of Barnabas:

Saint Barnabas is mentioned in the New Testament and he is very well admired too: "For God who was at work in the ministry of Peter as an apostle to the Jews, was also at work in my ministry as an apostle to the Gentiles.  James, Peter, and John, those reputed to be pillars, gave me [Paul] and Barnabas the right hand to fellowship when they recognized the grace given to me.  They agreed that we [Paul and Barnabas] should go to the Gentiles, and they to the Jews.  (The New Testament from the N.I.V Bible, Galatians 2:8-9)"

Saint Barnabas's story in the New Testament begins in Acts 4:36.  People often don't know the name of this great Saint. The reason for that is because he lived and dedicated his life to serve others. His real name was Joseph, but the Christians gave him a nickname of "Barnabas" because it meant the "son of encouragement".   Barnabas came alongside people in times of challenge and helped them; see Acts 9:10-28 and Acts 15:36-39 for more details.

So in other words, we really should take his Gospel very seriously and consider it too the inspired word of GOD.  Since Christians believe in Paul, John, Mark and Matthew as Prophets of GOD, then they should also consider Barnabas as a Prophet too.
