I am constantly amazed at your lack of understand and conflation of what the Scriptures say. It's as if you have no prior Biblical training at all.
It's as if the concept of context has no meaning for you.
All sins have been forgiven and covered for the believer in Christ.
Are there earthly consequences of our sins? Yes. If you're caught stealing you may go to jail.
Do you have to "serve time" after you die for this? Not per the New Testament....maybe in Roman Catholicism....but not Christianity....and there is a difference.
Romans 2:6Each person. Not "each unsaved person." Each person. This is not eternal punishment. It is temporal punishment.
"He (God) will render to each person according to his deeds.
2 Corinthians 5:10
For we must all appear before the judgment seat of Christ, so that each one may be recompensed for his deeds in the body, according to what he has done, whether good or bad.
We must ALL... so that EACH ONE ... whether good or bad --- This is not talking about eternal punishment. This is temporal punishment.
1 Peter 1:16-17
For it is written: Be holy, because I am holy. Since you call on a Father who judges each ones work impartially, live your lives in reverent fear during your temporary stay on earth.
Peter is here addressing the believing, Christian community. Children of God. They know that God is their Father.. and it is this Father, who will judge each one's work impartially.
Let me pose an example:
Al and Zack both commit a heinous crime, murder. The state tose who have done evil (as St. Paul says in Romans 13), puts them in prison.
Al repents of his sin, accepts Jesus as his personal Savior, is forgiven, is (as you would say) saved. Zack does not accept Jesus by faith, so of course is not saved.
Will God spring Al from prison but leave Zack in? Or is it still "just" for Al to serve out his sentence?
Should the State sremit Al's punishment on the grounds that the authorities are acting as God's instruments --- and Al is now a washed-in-the-blood-of-the-Lamb Christian, which (you say) means that temporal punishments are nullified?
Hasn't Al been washed clean and been given God's mercy? Should all of Al's temporal punishment be canceled, since his eternal punishment was canceled? Does "mercy" mean he should walk free?
Psalm 62:12
Also unto You, O Lord, belongs mercy: for You render to every man according to his work.
