Have you ever read this verse?

Anyone who has set aside the Law of Moses dies without mercy on the testimony of two or three witnesses. Hebrews 10:28
  
Please take note that this verse is in the NEW Testament. Yet, the writer of Hebrews specifically states that anyone who disregards the Law of Moses (the torah) DIESpresent tense - by the testimony of two or three witnesses – exactly as had happened in the Old Testament.
  
DIES =  avpoqnh,skw (apothnesko) to die
 
Therefore, how can “the law be done away”, as so many believers claim, if the New Testament states that it is still in effect?
