In the beginning of his book on how the gospel drives unity, Paul starts by talking about our relationship with God. Though at the core of disunity is our disunity from Him, God has addressed it by blessing us with spiritual blessings. The only reasonable response to them is to glorify Him, the most joyful thing we could possibly do with our lives.
