You say that we don’t have to abide by the Torah because Yeshua fullfilled it. You’re absolutely right we don’t have to abide by the Torah but not because He fullfilled it. Moses didn’t have to, Joshua, David, Elijah, Isaiah, Jeremiah etc didn’t have to either. But they understood that the Law is good and if we keep it we get the blessings instead of the curses as described in Deut 28. I know that Paul says we’ve already got all the blessings we need, which is true because salvation is it. This is found at the end of the OT: “Remember ye the law of Moses my servant, which I commanded unto him in Horeb for all Israel, with the statutes and judgments.”-Malachi 4:4
