Erlo Stegen emphasizes our indebtedness to share the Gospel, drawing from Jesus' Great Commission in Matthew 28 and Paul's acknowledgment of his debt to both Greeks and barbarians in Romans. He warns against living aimlessly without understanding our purpose, using parables to illustrate the folly of neglecting spiritual preparation for death. Stegen urges believers to not only teach others about Jesus' commands but to embody them in their own lives, reminding us that failing to do so makes us accountable for those we neglect. The sermon calls for a deep reflection on our responsibilities as Christians to spread the message of salvation and to live in accordance with God's commands.
