Jesus Preaches the Gospel to Nicodemus, Part 3

And as Moses lifted up the serpent. He explains more clearly why he said that it is he alone to whom heaven is opened; namely, that he brings to heaven all who are only willing to follow him as their guide; for he testifies that he will be openly and publicly manifested to all, that he may diffuse his power over men of every class. To be lifted up means to be placed in a lofty and elevated situation, so as to be exhibited to the view of all. This was done by the preaching of the Gospel; for the explanation of it which some give, as referring to the cross, neither agrees with the context nor is applicable to the present subject. The simple meaning of the words therefore is, that, by the preaching of the Gospel, Christ was to be raised on high, like a standard to which the eyes of all would be directed, as Isaiah had foretold, (Isaiah 2:2.) As a type of this lifting up, he refers to the brazen serpent, which was erected by Moses, the sight of which was a salutary remedy to those who had been wounded by the deadly bite of serpents…Christ introduces it in this passage, in order to show that he must be placed before the eyes of all by the doctrine of the Gospel, that all who look at him by faith may obtain salvation. – John Calvin
