John, Peter, Matthew.
The Messiah
Paul, a servant of Jesus Christ, called [to be] an apostle, separated unto the gospel of God, (Romans 1.1) James, a servant of God and of the Lord Jesus Christ, to the twelve tribes which are scattered abroad, greeting. (James 1.1) Simon Peter, a servant and an apostle of Jesus Christ, (2Peter 1.1) Jude, the servant of Jesus Christ, (Jude 1.1)
Because that was what the gospel writers said Jesus did and everything the Christians read in the Bible are taken as gospel truth. The gospel writers made Jesus go one better than Moses - Moses parted the water of red sea to walk on a dry land with the Jews escaping from Egypt - but Jesus performed 'a greater' miracle by walking on water.
Mark's Gospel portrays Jesus as fully human, adopted by God as his son at the time of his baptism. This gospel even has Jesus deny being God ("Why call me good, there is none good but God").Matthew and Luke portray Jesus as the Son of God from his conception, but not divine in the way that God was.John's Gospel portrays Jesus as divine and pre-existing, from the time of creation. In this gospel, Jesus frequently asserts his divinity.
Mark's Gospel has been called a book about the trial and crucifixion of Jesus, with a long introduction. In other words, the author of this Gospel focusses on the trial and crucifixion, providing only sufficient detail of the life and mission of Jesus in order to explain the context and reason for the crucifixion. Mark's theme is the power and authority of Jesus as the eternal son of God. Jesus Christ as the suffering servant.
The word "Gospel" means a proclamation preached by Jesus Christ. The 4 gospel writers are the 4 Apostles of Christ who recorded these preachings for us in the Bible. They are gospels of Matthew, Mark, Luke, and John are placed at the beginning of the New Testament and make up about half its total text.
Jesus was Himself the Gospel and 'the' preacher of the Gospel. He wrote no work or literature but lived what He taught. Others wrote about it later, particularly as they knew the Apostles would eventually die, and also to provide an authoritative record of truth against various heresies which were springing up. The works of the Gospel writers, two of whom were themselves Apostles and two not, were themselves 'Gospels of Jesus' in that they faithfully taught what Jesus said and did. There also were others present who could verify the truth of what was said and eager opponents who could disprove it if wrong.
He is the son of God our father and went to citys proclaiming the word. And the gospel is real so read it and become a faithful servant of the Lord.
The word gospel means "good news" which is the story of Jesus. The gospel is the story of the death, burial, and resurrection of Jesus Christ. There can't be a gospel that does not have the story of Jesus in it unless in is an incorrect gospel. All of the gospel books in the KJV Bible - Matthew, Mark, Luke, and John - have the story of Jesus in them.
The stories that bookend the Passion predictions in the Gospel of Mark are the healings of blind Bartimaeus and blind Bartimaeus performed by Jesus. By placing these miracles before and after the predictions of Jesus' suffering and death, the Gospel writer may be suggesting that true insight and understanding comes from recognizing Jesus as the suffering servant who brings healing and salvation to humanity.
St Matthew became a saint because he was one of the four gospel writers, and one of Jesus helpers, and also St Matthew preached the Good News, even after Jesus was crucified
All of the Gospel writers believed wholly in Jesus as the risen Christ. They had been witnesses or were recording the accounts of people who had witnessed directly the extraordinary events of the Resurrection and the following appearances of Jesus. Thus their belief was total and undeniable in all Gospels.
