How does God distinguish His people from the reprobate?

In the sermon, it is made clear that God's distinguishing grace is evident in the way He separates His people, Israel, from the Egyptians. This principle remains true today; God's election does not merely save but also sets believers apart. When God hardened Pharaoh's heart, it served His sovereign purpose, illustrating that He uses both the saved and the lost to fulfill His plans. God’s elect experience His grace in their lives, evidenced by the spiritual blessings they enjoy and the hope that ultimately secures their salvation compared to those who remain in rebellion against Him.
