Ephesians 2:4

Two small words turn the whole passage: "But God." In the verses just before, Paul has described people spiritually dead, walking according to the course of this world. The situation seems hopeless -- and then comes the great reversal. The decisive actor is God, and what defines Him here is mercy and love. He is "rich in mercy," the same language of abundance Paul used of grace in chapter one. Mercy is compassion toward the helpless; God possesses it not in trickles but in riches.

The verse then deepens with "his great love wherewith he loved us." Paul piles up the language deliberately -- great love, and a love actively exercised toward us, not held at a distance. This love is the engine of everything that follows in the chapter: the making-alive, the raising up, the seating with Christ. Notice that the verse describes God's motive before it describes any human improvement. We were not lovable first and rescued second; we were loved while still dead, and the love itself is what brings life. For the reader, this is the bedrock of assurance. God's saving action does not wait for us to clean ourselves up; it flows from who He is. The phrase "But God" remains the hinge on which every despairing story can turn.
