In this sermon, Peter explores humanity’s condition of walking and living in darkness, separated from God, using the metaphor of solitary confinement to illustrate spiritual disconnection. The good news of Christmas is revealed in the coming of the great light—Jesus Christ—who enters our darkness, bringing God’s presence, hope, and restoration. The effect of this light transforms lives, replacing fear with joy, renewing relationships, and offering abundant life and unending peace through the Messiah.
