What does it mean that God's people are the apple of His eye?

The concept of being the apple of God's eye signifies not only special affection but also profound protection. When God declares His people to be the apple of His eye, as shown in Zechariah 2:8, He asserts that anyone who harms them incurs His wrath. This assurance extends beyond mere affection; it embodies a promise of deliverance and safety. Understanding this relationship allows believers to grasp the depth of God's love, illustrating that His grace covers all aspects of their lives. It encourages believers to rest in the security that comes from being treasured by God, resulting in peace amid trials and a robust faith.
