I Am the Way, the Truth, and the Life
Jesus is the way to God, precisely because he is the truth of God (cf. notes on 1:14) and the life of God (cf. notes on 1:4; 3:15; 11:25). Jesus is the truth, because he embodies the supreme revelation of God—he himself ‘narrates’ God (1:18), says and does exclusively what the Father gives him to say and do (5:19ff; 8:29), indeed he is properly called ‘God’ (1:1, 18; 20:28). He is God’s gracious self-disclosure, his ‘Word’, made flesh (1:14). Jesus is the life (1:4), the one who has ‘life in himself’ (5:26), ‘the resurrection and the life’ (11:25), ‘the true God and eternal life’ (1 Jn. 5:20)
1A the state of one who is possessed of vitality or is animate. 1B every living soul. 2 life. 2A of the absolute fullness of life, both essential and ethical, which belongs to God, and through him both to the hypostatic “logos” and to Christ in whom the “logos” put on human nature. 2B life real and genuine, a life active and vigorous, devoted to God, blessed, in the portion even in this world of those who put their trust in Christ, but after the resurrection to be consummated by new accessions (among them a more perfect body), and to last for ever.
