Believers know they are God's people through faith in Christ and by experiencing the transformative work of the Holy Spirit.
Believers come to know they are God's people through the work of the Holy Spirit, who creates an awareness of their new identity in Christ. In 1 Peter 2:10, it is highlighted that those who were once estranged have now obtained mercy and become a people belonging to God. This change is evidenced by a transformed life, spiritual desires, and the ability to affirm one's faith in Christ as our only Savior. It is through faith that individuals are marked as those who belong to God, hence confirming their identity as His chosen people.
