Matt 5:18 "For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled."
If heaven and earth haven't passed away, it is imperative that we begin sacrificing animals, stoning adulterers, and following the Law to its letter.
What did "heaven and earth" mean to every First Century Jew? Simple Answer: The Temple...which passed away (destroyed by the Romans) in AD 70. Conclusion: "Heaven and earth" passed away LONG AGO!
