UPDATE: A new J.C. Ryle 365 Day Devotional has been released from Reformation Heritage Books. This devotional was taken from hundreds of J.C. Ryle's sermons. You can order the devotional HERE.
“Nothing darkens the eyes of the mind so much, and deadens the conscience so surely, as an allowed sin. It may be a little one, but it is not the less dangerous for all that. A small leak will sink a great ship, and a small spark will kindle a great fire, and a little allowed sin in like manner will ruin an immortal soul. Take my advice, and never spare a little sin.”
~ J.C. Ryle
