Isaiah knew his congregation. His word from the Lord spoke into the chaos and confusion of a people who had suffered not only a disruption of life, but also a disrupted understanding of God. Their cherished expectations of what it meant to be the covenant people had crumbled along with the destroyed Jerusalem. God had allowed this destruction of their naïve theology, and now they were exiled from both the land and the notion that God would protect them. It was this befuddled congregation that assembled to hear Isaiah’s sermons.
Life is details—phones that keep ringing, e-mail that has to be returned, computers that crash, copy machines that jam, and children who are sick when we need to be at work. We struggle with the details of bodies that don’t work as they should, with doctors, specialists, medical tests and pills. Our children juggle homework, athletics, orthodontists and piano lessons. Then we all go to church on Sunday, and what do we find but more details?
"A man had two sons . . .” was a common way to begin a parable, especially one comparing good and bad sons. Matthew uses it to contrast one son, who promises to work in the vineyard but never shows up, with another, who at first adamantly refuses to go to the vineyard but later repents and goes (21:28-32). Which one did the will of his father, asks Jesus? Not the one who talked a good game, but the one who actually followed through with obedient actions.
God will forgive my sins,” quipped Heinrich Heine on his deathbed. “It’s his job.” How different are the viewpoints of Isaiah, Paul and Luke! They note an ongoing theological tension between the assurance of God’s kindness and the call to immediate repentance. Yes, God is merciful, not punishing as we deserve, not automatically correlating our misdeeds with disasters. But there is no room for complacency: if we think we’re standing, we should watch that we do not fall.
The Hebrews’ stories brought their lives into balance. Moses believed that remembering where they’d been, how they’d come into the land God promised, and what God had done for them would keep them faithful. So he said that in offering the first fruits of harvest, “You shall make this response before the LORD your God: ‘A wandering Aramean was my ancestor; he went down into Egypt and lived there as an alien, few in number, and there he became a great nation, mighty and populous.’” Their story was a confession of faith, a community story that cast their thanksgiving into a framework that provided boundary and purpose to their lives together. It was a creed. Tell it again and again, Moses urged.
