Earlier quoted context omitted.
> but that Jesus had to suffer, to what, to make God decide to be more lenient with how he interprets our sins? Justice requires accountability for wrongs committed. When we break God's moral law, justice requires that we be held accountable. Jesus suffered for us to take the punishment that our sins require. Jesus took the penalty for us. That allows God to be a merciful judge, yet still fulfill all justice.
To punish one for the sins of another does not sound like justice to me, not does it hold the sinner accountable. A judge who kills his own son so that he could pardon the people that come before him is clearly insane. Doubly so if the judge is the same one who wrote the laws.
A man is convicted of a crime and the penalty is $1 million. Another man steps up and says he will pay the penalty.
In a way, you are right about it not being just. The convict deserves the punishment, but gets mercy instead. This is the nature of mercy and justice. They are opposed. Jesus paying for our penalty intertwines the two.
You obviously don't believe any of this is true or right. I don't make it my aim to convince you or anyone else. I'd be kidding myself if I thought I could do that. Just presenting Christian doctrine as accurately as I can.
