Despite regular practice of spiritual disciplines, I frequently get into a rut in my relationship with God. It's dangerous when God becomes routine and the Bible becomes boring and we hunker down to try to simply remember what we already know. The "o" in God begins to be pronounced "oh" instead of "awe".
A friend recommended a Bible study. Behold Your God is a 12 week curriculum consisting of daily workbook exercises and a weekly DVD lecture. It was produced by a guy I never heard of. After looking at the web site I decided it was probably yet another case of someone taking a few great doctrines, pre-digesting them to remove most of the flavor, putting them in a slick media package, and charging way too much.
Fortunately my parents are not as "discerning" as I am. They bought a set. We started the study as a family. Within a few days, I began realizing that this "guy I never heard of" was actually presenting meaty truths about God in a very penetrating, insightful way -- as if he did not merely know the truths, but had experienced them. He navigated through precarious theological concepts, where many another teacher has wandered into error, with remarkable precision and fidelity to Scripture.
The study left me with a new level of wonder about and joy in God. I have discovered more facets of His character that I have not yet explored. And it is clearer than ever how His character should affect mine.
Buy a set, find a few Christian friends, and dig in together. If you can't afford it, sell something! Seriously!
