John 3:14

If the Son of Man alone has this knowledge, how is it to be disseminated and become a light to all men? This is answered in the words, καὶ καθὼς Μωσῆς … τοῦ ἀνθρώπου [modern editors read Μωυσῆς; so also in LXX]. The emphatic word is ὕψωσε. When Moses made the brazen serpent, he did not secrete it in his tent and admit a few selected persons to view it, but ὕψωσε τὸν ὄφιν, gave it an elevation at which all might see it. So must the Son of Man, the bearer of heavenly light and healing, ὑψωθῆναι, that all may see Him. The “lifting up” of the Son of Man is interpreted in John 12:33 to mean His lifting up on the cross. It was this which drew human observation and human homage. The cross is the throne of Christ. In the phrase δεῖ ὑψωθῆναι the aorist is used in accordance with Greek usage by which an aorist infinitive is employed to express the action of the verb even though future after verbs signifying to hope, to expect, to promise, and such like. Thus Iph. in Aul., 462, οἶμαι γάρ νιν ἱκετεύσαι, where Markland needlessly changes the aorist into the future. Nicodemus could not see the significance with which these words were filled by the crucifixion. What would be suggested to him by the comparison of the Messiah with the brazen serpent might be something like this: The Son of Man is to be lifted up. Yes, but not on a throne in Herod's palace. He was to be conspicuous, but as the brazen serpent had been conspicuous, hanging on a pole for the healing of the people. His elevation was certain, but it was an elevation by no mere official appointment, or popular recognition, or hereditary right, but by plumbing the depths of human degradation in truest self-sacrifice. There is no royal road to human excellence, and Jesus reached the height He attained by no blare of heralds' trumpets or flaunting of banners or popular acclaim, but by being subjected to the keenest tests by which character can be searched, by passing through the ordeal of human life in this world, and by being found the best, the one only perfectly faithful servant of God and man.
