1. Go outside the camp (9-14)
We should resist getting carried away by new teachings about ceremonies, because we always have access to grace that can strengthen our hearts. In our lives of faith, we should not be ashamed to bear disgrace and be misunderstood and excluded by people, because Jesus was also rejected and suffered outside the city to make us holy. This world is not our permanent home.
2. A sacrifice of praise (15-25)
Finally, we should remember that thankful praise is an offering that always pleases God. Being gloomy and negative is not gospel holiness. We shouldn't make our leaders' job more difficult than it already is, but support them. We need to pray for each other continually, even those that seem strong. Our Lord Jesus will equip us with everything good for doing his will.
