What does the Bible say about two kinds of people?

In the Scriptures, there is a clear distinction between two kinds of people: those who are called God's people and those who are referred to as the people of the devil. In Exodus 8:1-5, God speaks to Pharaoh about His people, indicating that they are the ones He has chosen for Himself. This division is further affirmed in the parable from Matthew 13, where the good seed represents the children of God, while the tares symbolize the children of the evil one. Therefore, all humanity can be categorized into these two groups, with God's people being those elected to salvation and the others remaining in their sin under the authority of Satan.
