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:
John 20:31
"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."
"In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not."
The "word" is the English translation for the Greek "Logos," which means "reason" or "wisdom." It represents the aspect of God which mediates in this world and in its creation. Jesus is the word made flesh
