The law introduced the wrath of God. “because the law brings about wrath; for where there is no law there is no transgression.” (Romans 4:15)
The wrath of God was revealed towards man after the law was given in Exodus 19. If Israel didn’t keep the laws given to them then they would see God’s wrath. His wrath was an expression of his judgment over sin and on justice.
“and My wrath will become hot, and I will kill you with the sword; your wives shall be widows, and your children fatherless.” (Exodus 22:24)
Jesus came and introduced the New Covenant which was a way out of that previous stone-cold religion which could not endear intimacy with God.
But the wrath was emptied when the Old covenant was consummated in the destruction of the temple, priesthood and sacrificial institution.
“19 So the angel swung his sickle over the earth and gathered the grapes from the vineyard of the earth and tossed them into the great winepress of the wrath of God. 20 Then the winepress was stomped outside the city, and blood poured out of the winepress up to the height of horses’ bridles for a distance of almost two hundred miles. (Revelation 14)
“17 Then the seventh angel poured out his bowl into the air, and a loud voice came out of the temple of heaven, from the throne, saying, “It is done!” 18 And there were noises and thunderings and lightnings; and there was a great earthquake, such a mighty and great earthquake as had not occurred since men were on the earth. 19 Now the great city was divided into three parts, and the cities of the nations fell. And great Babylon was remembered before God, to give her the cup of the wine of the fierceness of His wrath. (Revelation 16)
The wrath of God is behind us now because one sacrifice has pleased the Father and put him in a good mood. The law is passed away and his wrath is completed in its funeral. He is no longer angry.
Just like the scriptures say about the New covenant. God remembers our sins and iniquities no more.
