Matthew 5:17
Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 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.
Most Christian denominations teach that Christ fulfilled the entire Law, making it unnecessary for Christians today to observe God’s laws, such as the Sabbath and Holy Days. However, this interpretation is not consistent with the above verse, which clearly says that the law must be in effect today because heaven and earth have not passed away and because not everything has been accomplished. Unfortunately, many people read this verse and disregard all of that, latching on to the word “fulfill,” and say that the entire Law has been “fulfilled” once for all by Christ, making it unnecessary for us to follow it. Even with this reckless overlooking of what is actually being said, they are still wrong – Christ has not fulfilled the entire Law… yet.
