Christian self-help books can be insightful, but I take them with a grain of salt. I have read a few in my time, if anything they solidified my opinion on the topic, or opened my mind. Whether I agree with it or not, I am open to learning more about myself spiritually and how it all related to God. When it comes to scholar literature (ie. journal articles by theologians, academic commentaries that have studied scripture) I will take more seriously because they have studied context, word translation and a general knowledge of religion, and Christian history. I do know that everyone interprets scripture differently, so I think that digging deep and finding original intended meanings can be help with discerning what is correct interpretation and what is false. I do not doubt the Holy Spirit's input when we read scripture, but like I said we all interpret and bring our own meanings to what we read. I guess I take a more post-positivist approach to scripture and look for objective evidence and derive meaning from it, rather than the constructionist interpretative approach.
