This must be what you're talking about. My good buddy Wamba answered your questions to my satisfaction (to whom you didn't reply), but I can take another shot at them.
No, we need to use biblical methods such as restitution.
Because we shouldn't just "forgive and forget" any punishments.
Criminals have to pay the consequences of their crimes: Christian or no Christian.
No. Every one should have the chance to be saved. Did the murderer's victim get that chance? Yes, but it was certainly cut short. The murderer needs to pay the God ordained consequences of his crime. He will have the chance to convert...right before he gets a short drop and a sudden stop.
You're right. Christ did teach to forgive. But Jesus was talking about individual relationships, not government policy toward criminals. Besides, you can only forgive someone to the extent they have hurt you.
- This is again talking about individuals, not Government policy. If someone sins against you (ie. lies) and then repents and asks for forgiveness, certainly forgive him. But if a man rapes a woman (a crime), and he is later caught and then repents and asks for forgiveness, the woman can forgive him but he has in no way voidated his punishment.
- Jesus was preaching from under the Law: i.e. "If you don't forgive, you won't be forgiven." We are under Grace, therefore Paul's teaching: "Forgive others, because God has forgiven you" is much more applicable to us dealing with other individuals.
Now that I've answered all of your questions, please begin to answer my new line of questioning:
Do you agree that God authorized Governments to punish criminals?
