This past Sunday I preached a more topical sermon on sin and said that I would share a few of the resources mentioned in that sermon. The book I pulled some ideas from was Ralph Vennings, The Sinfulness of Sin (Kindle, Paperback). It is a deeply theological and practical read. I highly recommend you pick it up and read through it with some friends. Take it a section at a time, and let the Lord use it to show you the ugliness of your corruption and the beauty of Christ and his work in you.
