This sermon explores the biblical command to "teach one another" as a fundamental practice of loving one another in Christian community. Using the metaphor of "wax on, wax off" from The Karate Kid, Dr. Tom Pace illustrates how teaching and learning together are habits that must be practiced repeatedly until they become second nature. The message emphasizes that every Christian has something to teach and something to learn, creating a community where wisdom, Scripture, and goodness are shared. The sermon challenges the congregation to move beyond passive learning from gifted teachers to active participation in mutual teaching and learning, thereby building a culture of goodness that transforms the entire community.
