Bible school in January

We started January with Bible School. Every staff member have to develop their knowledge of theology. In this year our lessons was introduction of New Testament. We talked about historical questions dealing with authorship, date, sources, purpose, destination, etc., in all books of the New Testament. It was so interesting. I enjoy to know more about God's Word. I hope I can use it in my personal bible study.
I would like to recommend a book that helped me a lot in this course. The book title is An Introduction to the New Testament by D.A. Carson & Douglas J. Moo.
