Ouch, James! Someone said it is not a feel-good book but a spanker, and I get why. But I would also say it could be a ‘feel-good’ book, mainly if your faith is backed up by action. There is assurance in the knowledge that you know your faith is not in vain, given that you are not simply folding your arms but taking steps to show your belief.
There is a lot more beyond faith — the book talks about double-mindedness, wisdom, pride, and so many other things. It is a book that one should go through and sit with from time to time.
