John 1:17

For the law was given through Moses; grace and truth came through Jesus Christ.

Christ was not only greater than the mighty John the Baptist, but was also transcendantly above the great law-giver, Moses. This verse does not mean that grace and truth were not evidenced by the law of Moses, but that the grace and truth through the Lord Jesus Christ far exceeded anything in the old dispensation. The great heroes under the old covenant, all of the majestic ceremonial of the Jewish system, as well as all the burden of the great prophecies reached the zenith of their meaning and fulfillment in Christ. The true knowledge of God the Father of all creation came uniquely in the Lord Jesus who could truly say, "He that hath seen me hath seen the Father!" (John 14:9). The very next verse is even a more forceful statement of the same truth.
