Jesus became the end of the Torah because He is the Living Torah.
For Christ is the end of the law for righteousness to every one that believeth.
Jesus then continues, "I came to fulfill the Law" (Matt. 5:17). In other words,
"I came to fill the Law full; to bring to full fruition all that the Law pointed
to pictorially and custodially." "I came to fulfill the Law, by being the
dynamic directive of God, the living Torah, in the lives of His People." To
"fulfill" means more than just to fulfill the promises and the prophecies
historically. It carries with it the theological meaning of completing,
actualizing, consummating the Law by becoming its full intended content.
The best thing I have ever read on the Law of God!! This will even dispel David Friedman's confusion.
There is no other book like the Bible in the world where you have to know the Author to understand the book. If Christianity were the religion of the Book then it would be no different than any other religion in the world. But, Christianity is Christ! It is the dynamic, personal Spirit of God functioning in man.
