God’s eternal and unchanging nature is love. In love he responds to sin and evil with anger; but in love he also finds a way to rescue sinners from his anger. On the cross, Christ faced the wrath of God, consuming it fully so no wrath is left for sinners who trust in Christ.
Before going to the cross, Christ prayed, “Let this cup pass from me” (Matthew 26:39). He prayed about the cup of God’s wrath, which is described by the Old Testament prophets: “Wake yourself, wake yourself, stand up, O Jerusalem, you who have drunk from the hand of the Lord the cup of his wrath, who have drunk to the dregs the bowl, the cup of staggering” (Isaiah 51:17); “Thus the Lord, the God of Israel, said to me, ‘Take from my hand this cup of wine of wrath, and make all the nations to whom I send you drink it” (Jeremiah 25:15); to Judah, God says, “You have gone the way of your sister; therefore I will give her cup into your hand. Thus says the Lord God: You shall drink your sister’s cup that is deep and large; you shall be laughed at and held in derision, for it contains much; you will be filled with drunkenness and sorrow. A cup of horror and desolation, the cup of your sister Samaria, you shall drink it and drain it out, and gnaw its shards and tear your breasts; for I have spoken, declares the Lord God” (Ezekiel 23:32-34). Imagine in heaven a cup with your name written on it. Every time you sin, a drop of poison falls into that cup, the poison of the wrath of God. For every lie, another drop of poison. For every careless deed that causes harm, another drop of poison. For every neglected opportunity to help a neighbor, another drop of poison. Imagine that cup of God’s wrath waiting for you when the Day of the Lord comes, the Day when all sinners will be judged.
But now that cup is empty. Jesus took your cup and drank all that it contained. In exchange, he gives you his cup, the cup of salvation (Psalm 116:13; I Corinthians 11:25-26). As in a comic movie, one cup is poisoned and the other is pure; but Jesus purposely takes the poisoned cup and gives to you and me the cup that is pure.
For this reason, Christians do not fear the wrath of God. Nor are we terrified of the Day of the Lord. Because Jesus drank the cup of wrath and gave us the cup of salvation, we are confident that we belong to the Lord and will dwell in his kingdom forever. The wrath of God is real; but Christians will never face that wrath. It was consumed and finished on the cross, granting us forgiveness, salvation, and eternal life.
No one can teach the whole message of Scripture without speaking of the wrath of God. God’s commandments (his Law) show us why we deserve his wrath; God’s promises (his Gospel) show us how we are spared his wrath through the saving work of Christ. God is love, which is why Christ provided an atoning sacrifice to save us from God’s wrath. No Christian should seek to be a wrath-monger; we should always delight to share the grace of God with sinners. The purpose of teaching the Law is to show our sins and our need for a Savior. This leads to repentance and the joy of sharing the Gospel, which shows us our Savior. The full message must be taught for sinners to come to repentance and faith and thus receive the Lord’s salvation. J.
