Secondly, The powerful remedy provided against this fatal malady. The case of poor sinners is deplorable; but is it desperate? Thanks be to God, it is not; there is balm in Gilead. The Son of man is lifted up, as the serpent of brass was by Moses, which cured the stung Israelites. 1. It was a serpent of brass that cured them. Brass is bright; we read of Christ's feet shining like brass, Rev_1:15. It is durable; Christ is the same. It was made in the shape of a fiery serpent, and yet had no poison, no sting, fitly representing Christ, who was made sin for us and yet knew no sin; was made in the likeness of sinful flesh and yet not sinful; as harmless as a serpent of brass. The serpent was a cursed creature; Christ was made a curse. That which cured them reminded them of their plague; so in Christ sin is set before us most fiery and formidable. 2. It was lifted up upon a pole, and so must the Son of man be lifted up; thus it behoved him, Luk_24:26, Luk_24:46. No remedy now. Christ is lifted up, (1.) In his crucifixion. He was lifted up upon the cross. His death is called his being lifted up, Joh_12:32, Joh_12:33. He was lifted up as a spectacle, as a mark, lifted up between heaven and earth, as if he had been unworthy of either and abandoned by both. (2.) In his exaltation. He was lifted up to the Father's right hand, to give repentance and remission; he was lifted up to the cross, to be further lifted up to the crown. (3.) In the publishing and preaching of his everlasting gospel, Rev_14:6. The serpent was lifted up that all the thousands of Israel might see it. Christ in the gospel is exhibited to us, evidently set forth; Christ is lifted up as an ensign, Isa_11:10. 3. It was lifted up by Moses. Christ was made under the law of Moses, and Moses testified of him. 4. Being thus lifted up, it was appointed for the cure of those that were bitten by fiery serpents. He that sent the plague provided the remedy. None could redeem and save us but he whose justice had condemned us. It was God himself that found the ransom, and the efficacy of it depends upon his appointment. The fiery serpents were sent to punish them for their tempting Christ (so the apostle saith, 1Co_10:9), and yet they were healed by virtue derived from him. He whom we have offended is our peace.
『Christ is the same. It was made in the shape of a fiery serpent, and yet had no poison, no sting, fitly representing Christ, who was made sin for us and yet knew no sin; was made in the likeness of sinful flesh and yet not sinful; as harmless as a serpent of brass.』
這段話的意思是：
基督也是一樣。它（銅蛇）被做成可怕的蛇的shape，但是沒有毒，沒有刺，能夠合適的代表基督，基督為我們成為罪，但是卻不知道罪；祂成為罪之肉身的likeness，但是卻不是有罪的；正如同銅蛇一樣無害。
嗯，請repentant『開刀』！
