Do not take revenge, my dear friends, but leave room for God’s wrath, for it is written: “It is mine to avenge; I will repay,” says the Lord- Romans 12:19
“God will lift from you the suicidal load of vengeance and carry it to one of two places. He will carry it to the cross, if the person repents, or He will carry it to hell, where they will be forever and you can’t improve on either of those.
If they are in hell, you do not need to add to their punishment. If they are love (?), born and forgiven and paid at the cross, you will dishonour the Lord if you do not share in the forgiveness.
This is a massive promise “I will repay”. And that is true for every single sin that has ever been committed, anywhere in the universe, at any time. That’s true of that God will repay that sin, either on the cross or in hell. It is one of the reasons why hell is such an important reality to know about.”
