In an interview with Dr. Sam Storms, author of Signs of the Spirit, in which he talks about Jonathan Edwards and his book about Edwards’ view of the spiritual life, he said that most people would recommend that people read Religious Affections for their first book by Edwards. He said this can be a little heavy for some and recommends Personal Narrative of Jonathan Edwards. This is a very short work of his own account of his early years and testimony to his own saving faith in Christ. It may be difficult to find in print but it’s a short read and is available online.
