The: Not that He said a way, as if there are "many paths to God," but neither did He say "my teachings are the way!
Way: He Himself is the road to God.
The truth: Again the exclusive. Any notion is true, relative to this one truth. Himself!
The life: What does this say about those "outside?"
He then emphasised, "No one comes (not goes) to the Father but by Me."
And, notice, He started off that statement with a phrase that fit the conversation disturbingly well!
A popular song some years back said, "Nobody's right if everybody's wrong." If right were a matter of opinion, then nobody could really, be right, could they? What would "right" mean? A plurality of opinion votes? 51%? Full agreement?
If we were to "campaign" for truth, then surely Jesus would have some great qualities as a teacher, but a lot of things He said about His own person and purpose don't let us stop there. While skeptics today doubt all the miracle stories and "I am" statements in the Gospels, we must remember that there were enough witnesses to those miracles, and to the Resurrection, that for the first several hundred years the Church didn't have to argue for His divinity, but His humanity. There seems to have been no doubt about the Resurrection, even among the enemies of the Faith. If the priests or the sect leaders could have opposed that notion, surely with their thousands of followers it would not have taken a week to find the body, but nobody seems to have even tried. Their concern, from all accounts, was for "damage control" /after the fact!/
So what do we do with this claim? As somebody put it, either He's a liar, a lunatic, or Lord of all. If His had been another messianic movement, then why was such love, and not power or authority His main thrust, even when His followers were ready to launch a revolt in His name? And surely, any other man would have confessed under the torture He endured, hoping at least for a quicker death. Besides that, a politico or scam artist would have been a bit more careful to tell people things they could understand, and not rock the boat so badly. He rocked everybody's boat, from the far left to the far right in religion and politics!
A lunatic, then? What He had to say was too consistent, and the root of mental illness seems to be a heightened sense of pride or self-preservation. He taught about "laying down one's life," and demonstrated it! A "great teacher" would have spent more time on discourses, but He basically affirmed the moral law and its foundation in the Jewish Bible, and went so far as to say it applies to our hearts as well as our hands, and that He was come to be the ultimate holocaust: the sacrifice victim that would finally take our sins away. Radical, but definitely not crazy.
Logically, that only leaves us with Lordship. But what do we do with that? History gives us three options. We may, like many of the rulers of that day, oppose His message (can we divide the Person from His message, if the Person is true?) in a scramble to maintain control regardless of either truth or consequences. For such a person, I have only the deepest pity. Others somehow insist on dis-believing these things based on things they have read or heard. Those who make this choice I would beg, on bended knee, to check your sources. There is a lot of publishing that is based on a writer's attempt to prove what they already choose to believe, but this is a matter much more important than merely picking opinions like sports teams, though some do enter into it that lightly.
The third option is simple belief. He has said it, and proven it, and history supports it. Belief though, is not a mere opinion, but a life: A life lodged within the Life!
