The People's Bible Commentary Series
Apart from a good study bible (see Lutheran Study below), this is hands down the best resource you can get on helping to understand the bible. It also serves as an excellent devotional way to read through the bible. See NPH's website for both hardcopy and ebook versions
If you're looking for short, 5 minute devoltional readings written by great pastors applying bible verses to your daily life, NPH's Meditations is the best resource out there. Published monthly, we offer free copies in the church sanctuary in the back.
