John 14:6

ἐγώ εἰμι … ἐμοῦ. “I am the way and the truth and the life: no one comes to the Father save through me.” I do not merely point out the way and teach the truth and bestow life, but I am the way and the truth and the life, so that by attachment to me one necessarily is in the way and possesses the truth and the life. “The way” here referred to is the way to the Father. He is the goal of all human aspiration: and there is but one way to the Father, “no one comes,” etc. καὶ ἡ ἀλήθεια, “and the truth,” primarily about God and the way to Him, but also as furnishing us with all knowledge which we now require for life. Thomas craved knowledge sufficient to guide him in the present crisis. Jesus says: You have it in me. καὶ ἡ ζωή, “and the life”; the death which casts its shadow over the eleven and Himself is itself to be swallowed up in life. Those who are one with Jesus cannot die. They are possessed of the source of the source of life. Further see Hort's The Way, etc., and Bernard's Central Teaching. οὐδεὶς ἔρχεται, “no one comes to the Father save through me” as the way, the truth, the life. It is not “through believing certain propositions regarding me” nor “through some special kind of faith,” but “through me”.
