What does the Bible say about the people of God?

The Bible presents the people of God as a specially chosen group, exemplified by Israel in the Old Testament who were set apart by God for His purposes. In Exodus 12, we see the Passover, which symbolizes God's covenant relationship with His people, indicating that they are prepared, redeemed, dependent on God, and ultimately delivered by His hand. Christ further emphasizes this in John 15:16, stating, 'You did not choose me, but I chose you,' which affirms the sovereign grace of God in selecting His own.
