What does the Bible say about being a chosen generation?

In 1 Peter 2:9, believers are referred to as a chosen generation and a royal priesthood. This designation emphasizes that those who believe in Christ have been selected by God and are set apart for His purposes. Being called a 'royal priesthood' signifies that Christians are not only able to approach God through Christ but also have the authority to offer spiritual sacrifices acceptable to Him. This identity reinforces the idea that all believers belong to God’s family, marked by His grace and mercy, and they are to live in a manner that reflects this divine calling.
