What does the Bible say about being part of a holy nation?

In 1 Peter 2:9, believers are referred to as a 'holy nation,' indicating that they are set apart by God as His special people. This passage emphasizes the identity of Christians as chosen by God, reflecting His sovereignty in salvation. The term 'holy' signifies that these individuals are not just part of any nation but are called to live in a manner that reflects God's holiness. They are a people that have experienced His grace and are to proclaim His praises as they grow in their faith and relationship with Him.
