No matter what guilt we may have from our old lives in sin, your crucifixion with Jesus Christ destroyed at all. Somebody might say that we get Scott free without any guilt nor need to pay for crimes if this be true. But that is not so. Our guilt did deserve a punishment. And the gospel teaches us that that punishment occurred in our crucifixion with Jesus Christ.
Sin does deserve judgment.
The guilty person must be judged. God is not unrighteous. And that is why Jesus Christ had to suffer on the cross. Sin deserves punishment. And in John chapter 12, when Jesus said, now is the judgment of this world, and then said, If I be lifted up from the earth, will draw all men unto me, he was telling us that the judgment of all men would be fulfilled and taken care of in his death on the cross.
