Until the coming of Jesus Christ, the Bible is like a piece of music whose dissonance begs for some final resolution into harmony. Redemptive history is like a symphony with two great themes: the theme of God’s passion to promote his glory; and the theme of God’s inscrutable electing love for sinners who have scorned that very glory. Again and again all through the Bible these two great themes carry along the symphony of history. They interweave and interpenetrate, and we know that some awesome Composer is at work here. But for centuries we don’t hear the resolution. The harmony always escapes us, and we have to wait.
The death and resurrection of Jesus Christ is the resolution of the symphony of history. In the death of Jesus the two themes of God’s love for his glory and his love for sinners are resolved. As in all good symphonies there had been hints and suggestions of the final resolution. That is what we have in Isaiah 53 seven hundred years before Jesus came.
