Fourth-century church father Saint Gregory of Nazianzus, prayed:
I am spent, O my Christ, Breath of my life. Perpetual stress and surge, in league together, make long, oh long, this life, this business of living. Grappling with foes within and foes without, my soul hath lost its beauty, blurred your image.
