The first modernized classic I have posted on this site. Thomas Chalmer’s The Expulsion of Sin By Means of a New Affection.
Why you should read it? If you struggle with sin and wish you could stop or find yourself tired of chasing after things in this world . Chalmers offers a view that concentrating on your merely ridding yourself of sin is doomed for failure. Instead, receive and revel in the love of God. In this, sin will be displaced.
