Why is the concept of being a chosen people important for Christians?

The idea of Christians being a chosen people is foundational to our identity in Christ. As indicated in Exodus 19:5-6, God declared Israel as His treasured possession, setting them apart for a holy purpose. In 1 Peter 2:9, this concept carries into the New Testament, where believers are referred to as a 'royal priesthood,' indicating their calling to proclaim God's praises and represent Him to the world. This identity offers profound assurance of value, belonging, and responsibility, highlighting our purpose in living out our faith in service and worship.
