Ummm. . . The Calvinists are desperately trying to resist God's wrath and justice?

In all of the churches that I have ever been to, the Calvinists are the ONLY ones who actually preach/discuss/teach about God's wrath against sin and his unrelenting justice. However, your view of unrelenting is different from ours. By God's unrelenting justice, we mean that He will punish the unjust/unconverted forever in Hell. He will not relent in His punishment of them. However, WE know that God's justice, while unrelenting, took the just punishment away from those who are saved and put in on His Son, Jesus, when He died on the cross. So, the justice of God against the sins of the elect was turned from them but His justice didn't just disappear, it went to Christ who paid for our sins in full. Unlike what you seem to be believe, we don't believe that God will turn His wrath against the elect. Why don't we believe this? Because He has already turned His wrath against Jesus.
I don't see what WE have to repent of in our theology concerning this issue, my friend.
