When God called his people out of Egypt, Exodus 19:1-6 tells us that he did so for a purpose. Not only so the Messiah would come from their ranks, but so that Israel might be His people reflecting His nature to the world, thus showing the world how great He is. Peter picks up on this theme in 1 Peter 2:9-10, reminding God’s people today that we are His people, on earth to declare the wonders of His Name to the world.
