The law is a curb mirror and guide. It curbs our evil destruction tendencies and shows us our falts, then guides us to the best way to live.
I think you might be getting moral and ceremonial laws mixed up. Stealing, murder, lying etc are mortal laws that Jesus doesn’t overthrow. He says he fulfills them, but not one for will pass away of them. Ceremonial and civil laws on the other hand are for the governing of Israel at a certain period in time. The sacrifices, cities of refuge, dietary laws, priestly organisation etc are not moral codes, but rules for how Israel the nation was to be run.
So when Paul says to not keep sinning, he’s saying it’s not now okay to kill someone, not that you shouldn’t poop in your home.
So “sins” can be either “mortal” or “ceremonial,” and the latter are, post Jesus’s death, ok? How did Jesus’ death affect the mortal sins, if at all?
Mortal sins have a different connotation in catholicism, so I’ll keep calling them moral sins instead, aka things that she immoral. Moral sins are things that hurt us and others. Jesus died to take the punishment for our sin on himself instead of us. But since moral sin still hurts us and others, we still shouldn’t do it. But when we do, we have forgiveness in Christ so that we don’t despair about our relationship with God.
Yes the ceremonial laws no longer apply, since we are not in old Israel. Even before Jesus’ time, the ceremonial laws concerning the Tabernacle didn’t apply. After Jesus, the rest were repealed.
