PART 2: (by John Bauer)
Here are some more scriptures with either explicit or implicit penal substitutionary language:
Romans 4:25 He was delivered over to death for our sins and was raised to life for our justification.
Romans 5:8-9 God demonstrates his own love for us, in that while we were still sinners, Christ died for us. Much more then, because we have now been declared righteous by his blood, we will be saved through him from God's wrath.
2 Corinthians 5:21 God made the one who did not know sin to be sin for us, so that in him we would become the righteousness of God.
Galatians 3:13 Christ redeemed us from the curse of the law by becoming a curse for us (because it is written, "Cursed is everyone who hangs on a tree") …
Ephesians 5:2 … [Christ] gave himself for us, a sacrificial and fragrant offering to God.
Ephesians 5:25 … Christ loved the church and gave himself for her …
Colossians 2:13-15 [God] forgave us all our sins, having canceled the charge of our legal indebtedness, which stood against us and condemned us; he has taken it away, nailing it to the cross. And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.
Hebrews 2:17 Therefore he had to be made like his brothers and sisters in every respect, so that he could become a merciful and faithful high priest in things relating to God, to make atonement [propitiation] for the sins of the people.
Hebrews 9:28 … Christ was offered once to bear the sins of many, …
1 Peter 2:24 He himself bore our sins in his body on the tree, that we may cease from sinning and live for righteousness. By his wounds you were healed.
1 Peter 3:18 Because Christ also suffered once for sins, the just for the unjust, to bring you to God, by being put to death in the flesh but by being made alive in the spirit.
1 John 2:2 [Jesus Christ] himself is the atoning sacrifice for our sins, and not only for our sins but also for the whole world.
Here, the Greek term ἱλασμός (hilasmos, atoning sacrifice) is not one-dimensional. Christ's atoning sacrifice not only satisfies God's wrath against sin (propitiation) but also removes the guilt and stain of sin (expiation). Christ Jesus "set us free from our sins at the cost of his own blood" (Rev 1:5). Moreover, propitiation is technically about turning aside God's wrath. But that raises the question: From where, and to where? And the answer is from us believers and to himself (and so God's wrath remains on those who reject the Son, John 3:36). Where do we find this idea that he turned God's wrath to himself?
Matthew 26:39-42 Going a little farther, he threw himself down with his face to the ground and prayed, "My Father, if possible, let this cup pass from me! Yet not what I will, but what you will." … He went away a second time and prayed, "My Father, if this cup cannot be taken away unless I drink it, then your will must be done."
The cup does not represent mere suffering or impending death. In continuity with the Old Testament prophets and Christ’s own vocabulary, this is the cup of divine wrath, the wine of God's anger mixed undiluted, the judicial penalty for covenant-breaking sin. Christ prays for its removal not out of weakness or dread of suffering but because the one without sin is about to undergo the full fury of the covenant curses on behalf of his sinful people. This is not assumed, it is (a) established by Old Testament prophetic usage, (b) continued by Christ's own language of "cup" as shorthand for atoning suffering, and (c) fulfilled narratively in his cry of abandonment under God's judgment. Christ Jesus exhausted the cup of God's wrath so that there is no condemnation left for those in him.
Isaiah 51:17 Wake up! Wake up! Get up, O Jerusalem! You drank from the cup the LORD passed to you, which was full of his anger! You drained dry the goblet full of intoxicating wine.
Zechariah 12:2 "I am about to make Jerusalem a cup that brings dizziness to all the surrounding nations; indeed, Judah will also be included when Jerusalem is besieged." [The NET notes that this imagery, a cup that brings dizziness, "is that of drunkenness. The LORD will force the nations to drink of his judgment and, in doing so, they will become so intoxicated by his wrath that they will stumble and become irrational." Sounds like the 21st century, too.]
According to the Eerdmans Bible Dictionary (1996), the cup represented divine judgment on sin, which the Father had given him to drink. The Dictionary of Biblical Imagery (1998) concurs that the cup is "used figuratively as a symbol of God's judgment against sin." It goes on to explain:
God is pictured punishing wicked, rebellious people by making them drunk (Isa 51:17, 22; Jer 25:15-16; Ezek 23:31-34; Mark 14:36). Drunkenness may seem a mild picture for divine wrath compared to the horrors of war, natural disaster, and disease that God [normally visits] on sinners. But, in a way, the cup of wrath is a particularly dark symbol of judgment. … God is seen personally handing sinners their destruction and forcing them to drink. In Jeremiah 25:27 God tells the nations, "Drink, get drunk and vomit, and fall to rise no more."
The image of the cup of wrath carries special horror because, unlike being overtaken by battle, earthquake, or plague, drinking is something a person does deliberately. Drunkenness implies a humiliating progression: people begin confident of their power to handle the wine, but it eventually masters them. In several passages that feature the cup of God's wrath, we see that sinners start out arrogant (see Ps 75:4-5; Jer 49:12-16; Rev 18:6-8) but lose any vestige of human dignity as they drink the cup God hands them "down to its very dregs" (Ps 75:8). They stagger and fall unconscious in the streets (Is 51:17-20); they are exposed and disgraced (Hab 2:16); they go mad (Jer 51:7); they are scorned and "walked over" by their enemies (Is 51:23). Yet clearly their own choices, not God's capricious anger, have precipitated their destruction.
When we remember the predominant use of cup imagery in the Old Testament, Jesus' repeated use of the word cup to signify his impending death takes on great significance. When he pleads, "Abba, Father … take this cup from me" (Mark 14:36), we realize that his anguish grows principally from the prospect of feeling the full weight of his Father's anger against sin fall on himself. His ordeal is especially poignant because he, alone among humankind, does not deserve God's wrath—yet he chooses to surrender to crucifixion, so that sinners can receive forgiveness. As the soldiers come to arrest him, humility and heroism mingle in his words: "Shall I not drink the cup the Father has given me?" (John 18:11).
Because Jesus drinks the cup of wrath, he can offer his followers the cup of the new covenant. "Drink from it, all of you," Jesus tells the disciples at the Last Supper. "This is my blood of the covenant which is poured out for many for the forgiveness of sins. I tell you, I will not drink of this fruit of the vine from now on until that day when I drink it anew with you in my Father's kingdom" (Matt 26:27-29). All who accept Jesus' sacrifice for themselves can appropriate the blessings of forgiveness, fellowship with God and other believers, and certainty of eternal life that this cup of the new covenant holds (1 Cor 11:25-26). But any who take Jesus' sacrifice lightly or reject it completely will find themselves drinking the cup of God's judgment (1 Cor 11:27-30; Rev 17:3-6; 18:6-8).
The cup Christ received was not a symbol of mere suffering or martyrdom, but the judicial outpouring of divine wrath reserved for covenant breakers. In willingly drinking it, he bore the full penalty of sin in the place of his people, satisfying the demands of God’s justice through penal substitution. This was not incidental but deliberate—a voluntary offering under divine appointment, whereby the wrath due to the elect was turned aside and exhausted in the suffering Servant. It was penal, it was substitutionary, and it was atoning: all for whom Christ drank the cup may instead drink the cup of blessing. But for those who reject him, the dreadful wine of wrath remains—undiluted, filled to the brim, unavoidable, and just.
