Matthew 5
18 I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.
The Law will be the same until the mission is accomplished-That mission? The death of the Son of God as wages for the world's sins and then his resurrection. Now that everything is accomplished the law can disappear.
Better not tell Paul that!!
Romans 3
31 Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.
Or if you prefer Wycliffe
Romans 5
31 Destroy we therefore the law by faith? God forbid [Far be it]; but we stablish the law.
Doesn't matter, all the versions say the same. By your argument, the Ten Commandments are null and void since they were in the Old Testament. The law exists with some changes. Do we sacrifice bulls, cows, and whatnot? No, because Christ was the Final Sacrifice for our sins.
