"Some people find no comfort in the prophets' vision of a future world. "The church has used that line for centuries to justify slavery, oppression, and all manner of injustice," they say. The criticism sticks because the church has abused the prophets' vision. But you will never find that "pie in the sky" rationale in the prophets themselves. They have scathing words about the need to care for widows and orphans and aliens, and to clean up corrupt courts and religious systems. The people of God are not merely to mark time, waiting for God to step in and set right all that is wrong. Rather, they are to model the new heaven and new earth, and by so doing awaken longings for what God will someday bring to pass."
