"Do not boast of riches if you have them, or of your important friends; but glory in God only, from Whom all good things come and Who, being the highest good, desires to give us Himself. Do not boast of beauty of body, which is soon disfigured by illness or age. Do not be proud of any talents or skills you possess, for in this way you displease God from Whom you have received them."
The Imitation of Christ, Book One, Chapter Seven
