I have been reading My Utmost for his Highest by Oswald Chambers, and it has been absolutely amazing. It has just one page for every day, making it a great addition to your daily Bible reading without overwhelming you. Oswald Chambers manages to fit a very deep and provoking thought into every day, and I have learned so much from him. I definitely recommend the book to all Christians who want to get closer to God. Expect to be challenged to change your lifestyle and thought-process!
