The best sermons are lived, not preached.
Listen carefully this week at church. Sermons are always full of ideas of how we can be better Christians. Take one or several of those ideas and practice them throughout the next week. Stop back next Sunday and receive your next assignment.
This is what you were called to do, because Christ suffered for you and gave you an example to follow. So you should do as he did.
1 Peter 2:21
