If “heaven and earth” haven't passed away, we have a backlog of Jubilee years to celebrate, “cities of refuge” to resurrect, and bleeding lambs to burn on an altar. Forget Sunday. We got to go back to the Sabbath rest on Saturday. Throw out your clothes that mix linen and cotton and kill your rebellious children. The Law of Moses has some serious instructions.
So why don't Christians obey every letter of the Law if Jesus said it all applies “until heaven and earth pass away”?
Before all you Theonomists who want to enforce Mosaic Law today start saying “I told you so” to Dispensationalists who dismiss the Law's applicability (is that even a word?), let’s make sure we hear what Jesus meant. The historical background is going to blow your mind. It will require you to put down your apocalyptic imaginations of meteors hitting earth and start seeing the world Jesus talked about.
