God does not change. His wrath is appeased in exactly the same way as it was appeased in Ezekiel 18.
“But if a wicked person turns away from all the sins they have committed and keeps all my decrees and does what is just and right, that person will surely live; they will not die. 22 None of the offenses they have committed will be remembered against them. Because of the righteous things they have done, they will live. 23 Do I take any pleasure in the death of the wicked? declares the Sovereign Lord. Rather, am I not pleased when they turn from their ways and live?” (Ezekiel 18:21-23)
When we start to trust and obey him, he forgives us. Love keeps no record of wrongs. How does a person trust and obey him today? They trust and obey him by trusting and obeying the Messiah whom he has sent.
