Love is swift, sincere, pious, joyful, generous, strong, patient, faithful, prudent, long-suffering, courageous, and never seeking its own; for wheresoever a person seeketh his own, there he falleth from love.
He that loveth, flieth, runneth, and rejoiceth. He is free, and cannot be held in. He giveth all for all, and hath all in all, because he resteth in one highest above all things, from whom all that is good flows and proceeds.
You are a man, not God; you are human, not an angel. How can you expect to remain always in a constant state of virtue, when this was not possible even for an angel of Heaven, nor for the first man in the Garden?
