The New Testament has nothing similar? The wrath of God has never ceased. Once we are dead we all have to stand before judgment. It matters what you do with Jesus in this life though, if you will stand or fall at judgement.
Discussion
Judgement after death is not comparable to actively killing people. Are there any examples of god actively killing a person or people that he wasn’t happy with in the New Testament?
Why the switch from taking direct action in the Old Testament to judging them after they die in the new?
It is comparable on an eternal time scale.
Ok, let’s assume I accept that argument. Still, why the switch?
God brought judgment on wicked people and nations, through different means (super natural, other humans etc) and established new covenants.
Different covenants different times.
The last covenant was established through the work of Jesus. Since that change God lives within the believers.
This is His last call to us to repent.
