"For this I was born, and for this I came into the world, to bear witness to the truth" (John 18:37). THE TRUTH! There is truth—truth that comes from outside the world and gives meaning to the world. The world doesn't make this truth. It doesn't shape or change this truth. It is THE TRUTH, not a truth for me and a different truth for you. But THE TRUTH for all of us. Unchanging, absolute.
There may have been a generation or a century when this simple implication of the text would not need to be stressed: that there is truth—truth outside of my own mind, truth that I don't create but discover, that I don't control but submit to. There may have been a time when we didn't have to proclaim this as part of the Christian message. But not today.
Jesus is the one way to God the Father. Salvation can be found only in Christ. Jesus as the truth fulfills the teaching of the Old Testament and reveals the true God. Jesus alone is the life who fulfills the OT promises of “life” from God. Jesus is able to give eternal life to all those who believe in him.
