"But though He had done so many signs before them, yet they believed not on Him: that the word of Isaiah the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed? For this cause they could not believe, for that Isaiah said again, He hath blinded their eyes, and He hardened their heart; lest they should see with their eyes, and perceive with their heart, and should turn, and I should heal them. These things said Isaiah, because he saw His glory; and he spake of Him. Nevertheless even of the rulers many believed on Him; but because of the Pharisees they did not confess it, lest they should be put out of the synagogue: for they loved the glory of men more than the glory of God. And Jesus cried and said, He that believeth on Me, believeth not on Me, but on Him that sent Me. And he that beholdeth Me beholdeth Him that sent Me. I am come a light into the world, that whosoever believeth on Me may not abide in the darkness. And if any man hear My sayings, and keep them not, I judge him not: for I came not to judge the world, but to save the world. He that rejecteth Me, and receiveth not My sayings, hath One that judgeth him: the word that I spake, the same shall judge him in the last day. For I spake not from Myself; but the Father which sent Me, He hath given Me a commandment, what I should say, and what I should speak. And I know that His commandment is life eternal: the things therefore which I speak, even as the Father hath said unto Me, so I speak."--JOHN xii. 37-50.
In this Gospel the death of Christ is viewed as the first step in His glorification. When He speaks of being "lifted up," there is a double reference in the expression, a local and an ethical reference.[6] He is lifted up on the cross, but lifted up on it as His true throne and as the necessary step towards His supremacy at God's right hand. It was, John tells us, with direct reference to the cross that Jesus now used the words: "I, if I be lifted up, will draw all men unto Me." The Jews, who heard the words, perceived that, whatever else was contained in them, intimation of His removal from earth was given. But, according to the current Messianic expectation, the Christ "abideth for ever," or at any rate for four hundred or a thousand years. How then could this Person, who announced His immediate departure, be the Christ? The Old Testament gave them ground for supposing that the Messianic reign would be lasting; but had they listened to our Lord's teaching they would have learned that this reign was spiritual, and not in the form of an earthly kingdom with a visible sovereign.
Accordingly, although they had recognised Jesus as the Messiah, they are again stumbled by this fresh declaration of His. They begin to fancy that perhaps after all by calling Himself "the Son of man" He has not meant exactly what they mean by the Messiah. From the form of their question it would seem that Jesus had used the designation "the Son of man" in intimating His departure; for they say, "How sayest thou, The Son of man must be lifted up?" Up to this time, therefore, they had taken it for granted that by calling Himself the Son of man He claimed to be the Christ, but now they begin to doubt whether there may not be two persons signified by those titles.
Jesus furnishes them with no direct solution of their difficulty. He never betrays any interest in these external identifications. The time for discussing the relation of the Son of man to the Messiah is past. His manifestation is closed. Enough light has been given. Conscience has been appealed to and discussion is no longer admissible. "Ye have light: walk in the light." The way to come to a settlement of all their doubts and hesitations is to follow Him. There is still time for that. "Yet a little while is the light among you." But the time is short; there is none to waste on idle questionings, none to spend on sophisticating conscience--time only for deciding as conscience bids.
