John Gill explores the concept of God's joy, emphasizing that while joy is attributed to God in scripture, it should not be viewed as a human passion but rather as a divine delight in His own nature, works, and people. He explains that God finds joy in Himself, in His creation, and particularly in the redemption of His people, highlighting the profound relationship between God and His covenant people. Gill illustrates that God's joy is not only a reflection of His perfection but also a source of strength and security for believers, culminating in the ultimate joy of salvation and eternal communion with Him.
