Chuck Missler's Ephesians Series
After finishing the Learn the Bible in 24 Hours series, we decided to move into Ephesians. The main motivation for jumping into this book was because we wanted to learn more about the church. The fact that this was a much more doable 8 hours of instruction was a perk.
Ephesians is a wonderful book of high and lofty and immensely practical. There's so much depth to this book and yet so much that we can immediately understand and apply to our lives. We learned a lot.
