Why is understanding who are God's people important for Christians?

Grasping the identity of God's people is crucial for Christians as it shapes our understanding of salvation and our relationship with God. In 2 Corinthians 11, Paul defends the true gospel against false apostles, who falsely claimed the title of God's messengers. By recognizing that not all who claim to be of Christ are truly His, believers are called to discernment. This understanding encourages genuine faithfulness, as seen in Revelation 2:9, which warns against those who claim to be true believers but are not. Furthermore, acknowledging that God's elect include a diverse group from many backgrounds fosters unity within the body of Christ, as expressed in Galatians 3:28.
