Though we are not totally sure the exact circumstances which gave rise to the writing of 1 John, what is very evident is that some, even by the end of the apostolic era, had turned from the true faith. Maybe they had given up on Jesus altogether, at the very least they had given up on the idea of God in the flesh in Christ and all that that truth calls us to. Jesus is the Word of Life. He is not the esoteric word (logos) of the popular philosophy of the day, he is not a God to make in an image that suits our ideas. He is the one who came and because he came as God in the flesh he is the one, and the only one, who brings life. He is the Word of Life and through him we have fellowship with the Father and with one another.
