I worked through the Bible in a year with the Bible Recap. I did it through the YouVersion app on my phone. I did it with a group called a D-group.
I recommend many of Jen Wilkin's studies. Our Bible study group will start in February with God of Freedom. We finish our study on Exodus. We completed the first half of the book in the Fall, and prior to that, we studied her studies of Genesis. God of Creation and God of Covenant.
As I look at all of the studies I have done recently, I am beginning to realize that Jen Wilkin has become my new favorite bible study author. She has surpassed Beth Moore's studies I have done. At the least, they are neck in neck.
I like Jen's approach because she isn't always asking me "how I feel about a verse." That drives me nuts. It doesn't matter how I feel about God's word. I need to know what it means and how to grow in the truth it reveals. If it provokes a feeling in me, great.
If you are interested in doing one of her studies, you can search for her by name. At least 4 books and 7 studies.
Additional studies I have done of hers and recommend:
Better a study of Hebrews
Sermon on the Mount
1 Peter a Living Hope in Christ
You can find them on her website or at Amazon.
If you are looking for a good book to read on Revelation, I recommend Revealing Revelation
