The sermon teaches that Christian faith is lived in community, not isolation, drawing on the idea of Ubuntu—that we become fully human through one another. The imperfect heroes of Hebrews show that God works through flawed people, so we need companions who encourage us, share our struggles, and challenge us to grow in holiness. Above all, Jesus is the ultimate guide and encourager who forms us into a community that supports one another and reflects God’s love to the world.
