I think every Christian has his or her favorite book in the Bible, maybe you can share something about what you have known about the book and what you have you got from the book?
One of my favorite books in the Bible is Romans.
It’s a kind of spiritual weapon for Christians who are fighting sipiritual warfare everyday. It explains core doctrines of Christianity. Whenever I read it, I can remind myself how sinful I am and How great God’s love and forgiveness are.
Romans, Apo.Paul letter to Romans contains most of the doctrines of Christian Faith.
