Back in college (I think) I started reading the devotional
My Utmost For His Highest by Oswald Chambers. I don't remember how I picked up on it. It is very good. It is not trendy and doesn't necessarily speak to any sort of specific issue of the day or particular struggle. It is deeper than that. Rather academic. Or maybe it just feels that way because it uses bigger more academic sounding words. Fluffy it is not. It is not necessarily something that encourages in a way that just puffs up. It can cut to the core in a way that challenges. I've recently started reading it again and it has not disappointed. Here's an excerpt from today:

"What our Lord wants us to present to Him is not our goodness, honesty, or our efforts to do better, but real solid sin. Actually, that is all He can take from us. And what He gives us in exchange for our sin is real solid righteousness."
Also, if you go to the
