“Paul told the Ephesians elders to “shepherd the church of God which He purchased with His own blood” (Acts 20:28). Who purchased the church with His blood? The antecedent of “who” is “God.” God was the Buyer, the Church was the purchase, and His blood was the price. The marvel is that the dying Lamb is God in a human body. The One who hung on the cross is the One who inhabits eternity, Immanuel―God with us.”
