Source: His Own Heart was Lecherous | Bible.org
One of the most powerful stories I have ever heard on the nature of the human heart is told by Malcolm Muggeridge. Working as a journalist in India, he left his residence one evening to go to a nearby river for a swim. As he entered the water, across the river he saw an Indian woman from the nearby village who had come to have her bath. Muggeridge impulsively felt the allurement of the moment, and temptation stormed into his mind. He had lived with this kind of struggle for years but had somehow fought it off in honor of his commitment to his wife, Kitty. On this occasion, however, he wondered if he could cross the line of marital fidelity. He struggled just for a moment and then swam furiously toward the woman, literally trying to outdistance his conscience. His mind fed him the fantasy that stolen waters would be sweet, and he swam the harder for it. Now he was just two or three feet away from her, and as he emerged from the water, any emotion that may have gripped him paled into insignificance when compared with the devastation that shattered him as he looked at her.
“She was old and hideous…and her skin was wrinkled and, worst of all, she was a leper….This creature grinned at me, showing a toothless mask.” The experience left Muggeridge trembling and muttering under his breath, “What a dirty lecherous woman!” But then the rude shock of it dawned upon him—it was not the woman who was lecherous; it was his own heart.
