A human being is holy, not because he or she triumphs by willpower over chaos and guilt and leads a flawless life, but because that life shows the victory of God’s faithfulness in the midst of disorder and imperfection. The church is holy . . . not because it is a gathering of the good and the well-behaved, but because it speaks of the triumph of grace in the coming together of strangers and sinners who, miraculously, trust one another enough to join in common repentance and common praise – to express a deep and elusive unity in Jesus Christ, who is our righteousness and our sanctification. Humanly speaking, holiness is always like this: God’s endurance in the middle of our refusal of him, his capacity to meet every refusal with the gift of himself.
