Gospel unity is only possible through gospel humility. Unity is one of the greatest gifts Christ has given His church, but it is also one of the most fragile. It doesn't fracture first in our actions toward others; it begins in the depths of our hearts and minds, which take the form of pride, self-interest, and the quiet demand to be at the centre of everything. From prison, Paul urges the Philippians to guard their unity through this inward humility, which flows from a gospel-transformed heart.
