13. No one hath ascended to heaven. He again exhorts Nicodemus not to trust to himself and his own sagacity, because no mortal man can, by his own unaided powers, enter into heaven, but only he who goes thither under the guidance of the Son of God. For to ascend to heaven means here, “to have a pure knowledge of the mysteries of God, and the light of spiritual understanding.” For Christ gives here the same instruction which is given by Paul, when he declares that

the sensual man does not comprehend the things which are of God,
(1 Corinthians 2:14;)

and, therefore, he excludes from divine things all the acuteness of the human understanding, for it is far below God.

But we must attend to the words, that Christ alone, who is heavenly, ascends to heaven, but that the entrance is closed against all others. For, in the former clause, he humbles us, when he excludes the whole world from heaven. Paul enjoins

those who are desirous to be wise with God to be fools with themselves,
(1 Corinthians 3:18.)

There is nothing which we do with greater reluctance. For this purpose we ought to remember, that all our senses fail and give way when we come to God; but, after having shut us out from heaven, Christ quickly proposes a remedy, when he adds, that what was denied to all others is granted to the Son of God. And this too is the reason why he calls himself the Son of man, that we may not doubt that we have an entrance into heaven in common with him who clothed himself with our flesh, that he might make us partakers of all blessings. Since, therefore, he is the Father’s only Counselor, (Isaiah 9:6,) he admits us into those secrets which otherwise would have remained in concealment.

Who is in heaven. It may be thought absurd to say that he is in heaven, while he still dwells on the earth. If it be replied, that this is true in regard to his Divine nature, the mode of expression means something else, namely, that while he was man, he was in heaven. It might be said that no mention is here made of any place, but that Christ is only distinguished from others, in regard to his condition, because he is the heir of the kingdom of God, from which the whole human race is banished; but, as it very frequently happens, on account of the unity of the Person of Christ, that what properly belongs to one nature is applied to another, we ought not to seek any other solution. Christ, therefore, who is in heaven, hath clothed himself with our flesh, that, by stretching out his brotherly hand to us, he may raise us to heaven along with him.

14. 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. ⁶²⁶²     “Sur toutes manieres de gens.” 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. The history of that transaction is well known, and is detailed in Numbers 21:9. 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. Hence it ought to be inferred that Christ is clearly exhibited to us in the Gospel, in order that no man may complain of obscurity; and that this manifestation is common to all, and that faith has its own look, by which it perceives him as present; as Paul tells us that a lively portrait of Christ with his cross is exhibited, when he is truly preached, (Galatians 3:1.)

The metaphor is not inappropriate or far-fetched. As it was only the outward appearance of a serpent, but contained nothing within that was pestilential or venomous, so Christ clothed himself with the form of sinful flesh, which yet was pure and free from all sin, that he might cure in us the deadly wound of sin. It was not in vain that, when the Jews were wounded by serpents, the Lord formerly prepared this kind of antidote; and it tended to confirm the discourse which Christ delivered. For when he saw that he was despised as a mean and unknown person, he could produce nothing more appropriate than the lifting up of the serpent, to tell them, that they ought not to think it strange, if, contrary to the expectation of men, he were lifted up on high from the very lowest condition, because this had already been shadowed out under the Law by the type of the serpent.

A question now arises: Does Christ compare himself to the serpent, because there is some resemblance; or, does he pronounce it to have been a sacrament, as the Manna was? For though the Manna was bodily food, intended for present use, yet Paul testifies that it was a spiritual mystery, (1 Corinthians 10:3.) I am led to think that this was also the case with the brazen serpent, both by this passage, and the fact of its being preserved for the future, until the superstition of the people had converted it into an idol, (2 Kings 18:4.) If any one form a different opinion, I do not debate the point with him.
