Jeremiah 31:31-34 - Homiletics

The new covenant.

I. THE GRANTING OF A NEW COVENANT . Hitherto the Messianic era with all its glories has been regarded as the development and perfection of earlier ages. Here, for the first time, it is revealed as the realization of an entirely new order. This is the first clear indication of the difference between the Law and the gospel which grew more distinct as the latter was better understood, till St. Paul accomplished his great work of finally severing the two. In these verses we have the first justification for dividing religion into two dispensations and the Bible into two "Testaments." They constitute a great landmark in the history of religious thought. To us who live in the Christian age they are further most practically valuable for the description they give of our high and peculiar privileges and the promises they contain of greater blessing yet to be unfolded. Still, it is important to observe that these privileges and blessings were not always enjoyed.

1 . Truth is eternal, but the knowledge of truth is progressive. Hence the religious ideas of the race change, widen, rise to higher visions. The Bible is a progressive revelation. Theology—the human interpretation of Scripture and speculation on Divine things—is also progressive. Christians must not be bound by the ipsissima verba of Old Testament texts. The Old Testament itself says that these shall be superseded. Christians of one age should not be fettered by the orthodoxy of an earlier age.

2 . God is changeless, but his modes of action vary according to the varying conditions of men. The same principles of justice and love ever pervade his dealings with his creatures. But, like the parent who changes his domestic regulations as his family grows older, God has new dispensations for the later ages of the human family. He educates his children through different standards. There must ever be milk for babes and meat for strong men. Children need restraints and simple instruction, which gradually give place to more freedom and confidence and higher teaching. These changing requirements are met by the suitable adaptation of God's revelation from age to age.

II. THE CONTENTS OF THE NEW COVENANT .

1 . The Law written in the heart takes the place of the Law written on the stone tables. Religion becomes more internal, spiritual, personal.

2 . The spread of the knowledge of the true God is to be universal.

3 . These results follow perfect forgiveness of sin. This is the peculiarly Christian and evangelical element of the new covenant. The Law can only be written on the heart after the old sin has been washed out. The enjoyment of spiritual religious knowledge must follow a renewal of the spiritual nature. These privileges were impossible under the Law, because no outward ordinances, no "blood of bulls and goats," could take away sin. But when Christ came as the perfect Sacrifice, "the Lamb of God that taketh away the sin of the world," and brought in perfect forgiveness, he made it possible for us to enjoy the inward vision and brought the privilege within the reach of all men.
