„A man watches a bird flying, and wishes to fly himself, but he cannot, because he has no wings. Even so the will is present with a man to be pure, and blameless, and without spot, and to have no wickedness in him, but to be always with God; but he has not the power. To fly into the air of God and the liberty of the Holy Ghost may be his wish, but unless wings are given him, he cannot. Let us then beseech God to bestow upon us the wings of a dove, even of the Holy Ghost, that we may fly to Him and be at rest, and that He would separate and make to cease from our souls and bodies, that evil wind, which is the sin that dwelleth in the members of our souls and bodies. None but He can do it.“
