Paul Washer has a new book available online titled The Truth About Man (A Biblical Study of the Doctrine of Man).
The great goal of this study is for the student to have an encounter with God through His Word. Founded upon the conviction that the Scriptures are the inspired and infallible Word of God, this study has been designed in such a way that it is literally impossible for the student to advance without an open Bible before him or her. Our goal is to obey the exhortation of the apostle Paul in II Timothy 2:15: “Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth.”
It’s solid food cover to cover. By the way, be sure to read the Introduction– especially if you have ever wondered about the importance of studying Biblical doctrine.
