8当以色列人被火蛇所咬时,他们在神眼中就成了蛇。他们是属于蛇的,且有蛇的性情。然而,那条铜蛇只有蛇的形状,没有蛇的性情。所以,铜蛇能作基督的豫表;祂有罪之肉体的样式,形状,却没有罪之肉体的罪性。铜蛇被挂在竿子上,这竿子表征十字架。因此,在旷野里有一条铜蛇挂在竿子上,这在豫表中,描绘了在十字架上的顶替。挂在竿子上的铜蛇指明成为属于蛇的以色列人,被放在竿子上,但在其上他们被只有蛇形而没有蛇毒的东西所顶替。民数记二十一章写成后,过了许久基督来了;在祂与尼哥底母的一对话中,祂说到铜蛇的豫表。主耶稣似乎对他说,『尼哥底母,竿子上的铜蛇这幅图画,表征我要为你作的。那条蛇成了你先祖的顶替,叫他们得救脱离死,并得著生命。我要为你作同样的事。我要在十字架上死,顶替你,好叫你得著永远的生命。』主耶稣对尼哥底母说这话的时候,尼哥底母不太可能明白这事。尼哥底母必定没有看自己是一条蛇,他看自己是一个合乎道德的正人君子,到主耶稣这里来为了得改良行为的教训。然而,主耶稣论到铜蛇的话,似乎是对尼哥底母说,『你不该看自己是正人君子,反而要晓得你是一条蛇。当亚当在园子里被蛇咬的时候,你就成为蛇了。因为你有蛇的性情,我来不是要教导你,乃是要顶替你。在神眼中,你乃是蛇。我要顶替你,就需要在蛇的形状里被举起来。』我们若知道基督是铜蛇这豫表的应验,在罪之肉体的样式里而来,在十字架上受死,顶替并代替我们,这对我们乃是极大的祝福。亚当为蛇所咬时,我们都成了蛇。基督已经来顶替了我们,我们也信入了祂。在这里,我们需要问一个有趣的问题:我们这些相信基督的人还是蛇么?这问题的答案乃在于:我们现在是在说到铜蛇的约翰三章呢,还是在说到来主这里喝水的约翰七章?(约七37~39。)我们若饮于活水,就不再是蛇。但我们若缺少活水,我们就是争闹的蛇。
8When the children of Israel were bitten by the fiery serpents, they became serpents in the eyes of God. They were serpentine and had the serpentine nature. The bronze serpent, however, had only the form of a serpent but not the nature of a serpent. Therefore, the bronze serpent could be a type of Christ, who had the form, the likeness, of the flesh of sin but not the sinful nature of the flesh of sin. The bronze serpent was put on a pole, which signifies the cross. Thus, in the wilderness there was a bronze serpent on a pole, portraying, in type, a replacement on a cross. The bronze serpent on the pole indicated that the children of Israel, who had become serpentine, were put on the pole where they were replaced by something that had the form but not the nature of a serpent. Long after Numbers 21 was written, Christ came, and in His conversation with Nicodemus He referred to the type of the bronze serpent. The Lord Jesus seemed to be saying to him, ‘‘Nicodemus, the picture of the bronze serpent on a pole signifies what I will be for you. That serpent was the replacement of your forefathers so that they could be saved from death and have life. I will do the same for you. I will die on the cross as your replacement so that you may have eternal life.’’ At the time the Lord Jesus spoke this word to Nicodemus, it is not likely that he understood it. Nicodemus surely did not regard himself as a serpent but as an ethical gentleman who came to the Lord Jesus for the purpose of receiving teachings about his behavior. However, in His word concerning the bronze serpent, the Lord Jesus appeared to be saying to Nicodemus, ‘‘You should not consider yourself a gentleman but realize instead that you are a serpent. You became a serpent when in the garden Adam was bitten by the serpent. Because you have a serpentine nature, I have come not to teach you but to be your replacement. In the eyes of God, you are a serpent. As your replacement, I will be lifted up in the form of a serpent.’’ It is a great blessing for us to know that, as the fulfillment of the type of the bronze serpent, Christ came in the likeness of the flesh of sin to die on the cross as our replacement and substitute. When Adam was bitten by the serpent, we all became serpents. Christ has come to be our replacement, and we have believed into Him. At this point we need to ask an interesting question: Are we who believe in Christ still serpents? The answer to this question depends on whether, in our experience, we are in John 3, which speaks of the bronze serpent, or in John 7, which speaks of coming to the Lord and drinking (vv. 37-39). If we are drinking of the living water, then we are no longer serpents. But if we are short of the living water, then we are contending serpents.
