The fourth, and last, of the Gospels is that of John. It was written about 50 years after Jesus' ascension by the last surviving of His disciples, the apostle John; "the disciple who Jesus loved".
At the time John was writing, the Christian faith had spread and its followers were suffering at the hands of the Roman government. Despite this, John still hoped to spread the good news about Jesus, as He had commanded His disciples after His resurrection. As John says:
"but these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name."
