What does the Bible say about God's people being His jewels?

In Malachi 3:17, God declares, "They shall be mine in that day when I make up my jewels." This metaphor illustrates how God views His people as rare and valuable treasures, much like exquisite jewels crafted by skilled artisans. The comparison to jewels underscores the worth and significance of believers, who are considered the glory of Christ (2 Corinthians 8:23) and are fashioned with the grace of the Holy Spirit. The imagery suggests that God's people possess inherent value, being formed into a beautiful reflection of His character through His ongoing work of grace.
