One advantage to travelling on the train is that I have lots of good reading time. I've been reading a few different things, including 1 & 2 Samuel.
1 & 2 Samuel were originally one book. The book is set 1200BC-ish - Samuel is a priest and the last of the judges that God appointed to look after his people, the Israelites. The books of Samuel document the life and times of Israel's first two kings, Saul and David.
Like Genesis and Judges, the book of Samuel is non-stop action. It is so fast that I had to put some effort into maintaining a mental timeline as the book spans about a hundred years of history. The author tends to deal with one plot at a time, although there are several themes that the author returns to time and time again: Gods' holiness, his judgement, his patience and the way he keeps promises.
There are plenty of good commentaries available on the books of Samuel, so I'll spare you further detail. However, there are lots of memorable things. Here is my list from 1Samuel.
All in all, Samuel is definitely worth a read. Lots to learn about how God dealt with his people in Old Testament times, and lots to ponder about what it means to us in New Testament times.
