What does it mean to be a peculiar people in the context of the church?

The term 'peculiar people' as described in Titus 2:14 signifies that believers are distinct or set apart due to their reliance upon the grace of God for salvation rather than their own merit. This distinction is a result of the transformative work of the Holy Spirit, leading Christians to live in a way that honors God. As this peculiarity manifests in zealous good works, believers reflect Christ's character and are called to serve as witnesses in a world that may not understand their faith.
