Old Testament? New Testament? Yes!

The unity, and the real meaning of the historical revelation of the Old Testament cannot be understood from the Old Testament itself, but only from the standpoint of Jesus Christ, just as, conversely, Jesus cannot be known as Christ where He is not understood as the One who fulfils the Old Testament revelation through history. But this only becomes completely clear when we grasp the unity and differences of the two Testaments from the standpoint of the contrast between the Law and the Gospel.—Emil Brunner, The Christian Doctrine of Creation and Redemption, 208
