The document discusses Jesus preaching about the kingdom of God. It provides several Bible passages where Jesus teaches about and heals people in the name of the kingdom of God (Matthew 4:23, Acts 1:3). It encourages making God's kingdom the central message and idea, personalizing it, studying it, and thinking of the church as coming from the kingdom rather than the other way around. The overall message is that the kingdom of God should be our highest priority and focus.
