A good place to start your study of Scripture would be with a book study. Many groups begin with a Gospel such as Mark (22 studies by Jim Hoover) or John (26 studies by Douglas Connelly).

Later you might want to come back to it. You might prefer to try a shorter letter. Philippians (9 studies by Donald Baker), Ephesians
