The bronze serpent (which Moses erected in the Negev desert) on Mount Nebo created by the Italian artist Giovanni Fantoni, visually merging the healing bronze serpent set up by Moses in the desert, and the Crucifixion of Jesus.
“In any case, the center of gravity in stories from Numbers in the Old Testament (Bronze Servant) and the Gospel (“For God so Loved the world” — and the key link between them — is the saving action of God, as well as God’s intention to save not just a select few but rather “everyone” who looks upon the bronze serpent (Numbers), and indeed the entire world (John).”
To make his case, Jesus alludes to the Israelites in the wilderness (Numbers 21) and to Abraham and Isaac (“gave his only Son”; John 3:16; Genesis 22)… Jesus puns on the phrase, “lifted up”: Moses lifted up the bronze serpent and Jesus will be lifted up on the cross, and at the same time the phrase also alludes to Jesus’ resurrection and ascension (John 3:14). Above all, however, the reference to the story from Numbers highlights God’s character as the One who saves even and especially in the face of rebellion. The Israelites had self-destructively turned against God, but when they asked for deliverance from the consequences of their sin (and please note, their plea isn’t out of any high-minded piety, but rather is driven by self-preservation!), God gracefully delivers them.”
“As we move through Lent toward Holy Week, this passage provides another angle on how to think about Good Friday and Easter Sunday. The reference to the story in Numbers points to the cross and resurrection as divine acts of love and mercy for the sake of all — even and especially those who are caught up in sin’s self-destruction, not the best and brightest and most pious. And the reference to the story of Abraham and Isaac (“gave his only Son”) points to the cross and resurrection as signs of God’s extravagant faithfulness and devotion to humanity. In short, God loves “in this way” (houtos): graciously, mercifully, faithfully, devotedly — and universally, for the sake of “the world” (kosmos).
“There’s a fascinating theology of the cross evoked here, distinct from both “penal substitution” theory (the idea that Jesus absorbs punishment on our behalf) and “Christus Victor” theory (the idea that Jesus conquers the powers of death). While God could have saved the Israelites by having them look upon any object at all, or in some other way entirely, the chosen remedy is to look upon a bronze serpent, a vivid reminder — even in the midst of healing and restoration — of two things: first, the deadly, self-destructive nature of sin; and second, God’s gracious transformation of even our worst into part of our redemption. Likewise, the Christian cross can play this dual role, reminding us of the many ways we turn against each other in violence and betrayal, and at the same time, of God’s graceful, transformative forgiveness and deliverance. ”
“Think of it this way: the bronze serpent takes what was for the wandering Israelites one of the very worst things in the world (a lethal snake) and remakes it into one of the very best (an instrument of healing). Accordingly, the Christian cross can be understood as an imperial weapon of torture and death divinely transformed into a sign of hope and new life, a sword remade into a ploughshare. Viewed this way, the cross epitomizes and proclaims the Great Reversal now underway: God is turning the world around, redeeming even the worst of the worst, swords into ploughshares, serpents into salves, crosses into trees of life — making all things new.”
