Division is the cultural cancer that weakens the church, but Jesus has already torn down the walls of hostility. From 1 Corinthians and John 17, we saw that love is the faith-supplement that builds spiritual immunity: it chooses patience, kindness, humility, truth, forgiveness, and endurance so a diverse body can live as one. Unity is not sameness. It is Spirit-formed oneness that becomes our public witness in an us-versus-them world.
