What does the Bible say about being a peculiar people?

In 1 Peter 2:9, the Apostle Peter defines believers as a 'chosen generation, a royal priesthood, a holy nation, a peculiar people.' This term 'peculiar' translates to 'purchased possession,' indicating that Christians are distinct because they have been bought with the precious blood of Christ. The significance of being a peculiar people lies in the understanding that our identity and assurance of salvation stem from God's sovereign grace and our union with Christ. We belong to Him, and this defines our purpose, ethics, and values that are contrary to those of the world.
