For the past 6 weeks, I've been reading and pondering the book of Exodus. If you are unfamiliar with the Old Testament, it's the account of Moses and the Israelites' journey from slavery in Egypt to the Promised Land.
I've been using a study booklet (from the NavPress LifeChange series) that was created by the publishing arm of the Navigators.
The Navigators are an interdenominational Christian ministry that was founded in the 1930s by a Californian named Dawson Trotman. Mr. Trotman taught Sunday School, ministered to youth groups, and also had an outreach to sailors in the U.S. Navy. He was known for encouraging folks to memorize Scripture.
So back to my impression of the Exodus booklet - it is brimming with historical information (like tidbits about the Tabernacle), chock-full of study questions, methodical, nearly 170 pages long, and even includes maps. To boot, NavPress has avoided the PC claptrap that currently permeates InterVarsity Press Bible study booklets.
If you are interested in material that breaks down and clarifies confusing Scripture passages, is theologically sound, and encourages one to 'dig deep', I highly recommend the LifeChange series.
Here are several of their best sellers.
