This sermon emphasizes the importance of theology during Advent, particularly the greatness of God, and how seeing Him clearly transforms our hearts and actions. Through the "Four G's" framework—God is Glorious, Great, Good, and Gracious—the message invites believers to trust God fully and find freedom from fear, control, and the need for self-sufficiency. By viewing Jesus as both the Lion of Judah and the Lamb of God, we grasp the balance of His greatness and goodness, enabling us to respond with belief, love, and obedience, especially during the Advent season.
