"Thy Kingdom come. By this sweet word we obviously offer God this prayer: Let the opposing battle front be broken and the hostile phalanx be destroyed. Bring to an end the war of the flesh against the spirit and let the body no longer harbour the enemy of the soul. Oh, let them appear, the royal force, the angelic band, the thousands of rulers, the myriads of those who stand on Thy right hand, that a thousand warriors may fall on the front of the enemy! Strong, indeed, is the adversary, formidable, yea, invincible to those bereft of Thy help. Yet only as long as man is fighting alone; when Thy Kingdom comes, the pangs and sighs of sorrow vanish, and life, peace, and rejoicing enter instead."
--St. Gregory of Nyssa, On the Lord's Prayer III
