The theologian John Mackay once described the book of Ephesians as “the distilled essence of the Christian religion, the most authoritative and most consummate compendium of our holy Christian faith.” Writing to a church facing timeless challenges, the apostle Paul set out to remind his readers of all that God has accomplished for us in Christ—and what we then do and become in response. Throughout history, the resulting six chapters have brought countless people to an understanding of their place in the purposes of God and the wonders of His grace and peace.

These tools equip us to push back the darkness and direct others to the Light of the World, Jesus.
