Here is a brief video explaining the NT picture of the relationship between the OT Law and what Jesus accomplished.
(Below is the bottom line and some recommended resources)
- Jesus did not come to “annul” or “overturn” the OT Law, He came to “completely fulfill it unto its intended end” (Matt 5:17)
- In His death on the cross, Jesus makes our relationship to the law the same as the binding nature of a widow to her departed husband. (Eph 2:15)
- The Old Covenant was made “obsolete” by the New Covenant in that it is no longer useful for picturing God’s eternal law (His character) since that function was more fully expressed in His Son. (Heb 8:13)
There is much more that can be said about this topic, I would point you to these resources (below). Please do interact with questions/comments in the “comments” section below. I hope to post another video in a week or two.
