I am the way the truth and the life, no one comes to the father except through me.A bit of commentary on John 14:6 by John Gill:
the way - Christ is not merely the way, as he goes before his people as an example; or merely as a prophet, pointing out unto them by his doctrine the way of salvation; but he is the way of salvation itself by his obedience and sacrifice; nor is there any other
the truth - he is not only true, but truth itself. he is the sum and substance of all the truths of the Gospel; they are all full of him, and centre in him; and he is the truth of all the types and shadows, promises and prophecies of the Old Testament; they have all their accomplishment in him; and he is the true way, in opposition to all false ones of man's devising.
the life - Christ is the author and giver of life, natural, spiritual, and eternal; or he is the way of life, or "the living way"; in opposition to the law, which was so far from being the way of life, that it was the ministration of condemnation and death: he always, and ever will be the way; all in this way live, none ever die; and it is a way that leads to eternal life
