“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)
So even though we are forgiven, when we start to trust and obey God, he forgives us. Love keeps no record of wrongs. So how does a person trust and obey God today? They trust and obey him by trusting and obeying the Messiah whom he has sent.
