The sermon emphasizes the significance of name changes in Scripture as reflections of encounters with God. It highlights how Abram becomes Abraham, signifying the transformation of a barren father into the father of nations through faith. Jacob’s transformation into Israel illustrates a shift from deception to divine covenant after wrestling with God. Saul’s encounter on the road to Damascus changes him into Paul, emphasizing a new calling marked by suffering. Lastly, Simon’s recognition of Jesus as the Messiah leads to his name change to Peter, affirming his identity and authority. The sermon encourages believers to anticipate their own encounters with God, which can lead to identity changes and the fulfillment of divine promises.
