In this sermon Luther preaches on the words of Jesus about worry and avarice. Jesus commands us to work and not worry, while we always worry without working.
Jesus heals a deaf and mute man, and Luther preaches about it. The first part of the sermon reminds us that while the devil is working to destroy everything good, the Lord Jesus is fighting back. The second part of the sermon extols the external Word.
False prophets attack the church, the state, and the family. Luther shows how, and also unfolds the two rules that Jesus gives for keeping the false teachers at bay.
