God is without sin. If people continue to sin. He has to send a strong message to stop. That’s what God’s wrath is.

Psalm 60:

1 You have rejected us, O God, and broken our defenses.
You have been angry with us; now restore us to your favor.
2 You have shaken our land and split it open.
Seal the cracks, for the land trembles.
3 You have been very hard on us,
making us drink wine that sent us reeling.
4 But you have raised a banner for those who fear you—
a rallying point in the face of attack. Interlude
5 Now rescue your beloved people.
Answer and save us by your power.
