What does the world really need? It needs nothing but the full-on advent of God himself. This sermon explores how Christians are reduced to praying only for that. It, therefore, interacts with modern optimism, which is not sure that the end of this world is really necessary. It also looks at the way that Isaiah spiritually and prayerfully prepares Christian hearts for the final advent of the Lord. He does this magnificently, taking on our self-righteously and pointing us to Christ who is our only true righteousness.
