Christology of 1 John

Another good quote from Martin Hengel:

'The first letter of John, which takes the intentions of the Gospel further, defines this precisely: “Whoever does not love does not know God; for God is love. In this the love of God was made manifest among us, that God sent his only-begotten Son into the world, that we might love through him (4.8ff). This means that in the Son who has become human, God’s love, his very nature, has become manifest for humankind; God himself comes to them. The incarnation of the love of God, not the deification of Christ, is the main theme of Johannine theology.'
