O fair sun, and fair moon, and fair stars, and fair flowers, and fair roses, and fair lilies, and fair creatures! but O ten thousand, thousand times fairer Lord Jesus! Alas, I wronged him in making the comparison this way. O black sun and moon; but O fair Lord Jesus! O black flowers, and black lilies and roses; but O fair fair, ever fair Lord Jesus! O all fair things, black, deformed, and without beauty, when ye are set beside the fairest Lord Jesus! O black heaven, but O fair Christ!
