Some of the best devotional books are the ones that need dug up from a by-gone age. This has been my experience. Today we live in an age where spiritual exposition and communion are largely unknown. There is a forgotten life of spiritual devotion. From ministers to new converts it's an age of human interaction and not Divine interaction. Maybe you have felt down or depressed when it comes to devoting some private time to God? Spiritual devotion is difficult in this world of me, me, me... but the Lord by His Spirit can enlighten us through another's eyes.

To this end I'd like to recommend a devotional book by Rev Horatius Bonar. It is a very simple work for devotional needs. He uses one verse or so as his base text and then goes on to talk about the text in a sermon format. However, it is unlike a sermon in as much as Bonar uses the most flowing and picturesque language. He is not stiff at all. Every one of his devotional doses have gone down easy. They are also eminently practical; making you think and consider your soul in light of the truth presented. His electric prose here is matched only by the spiritual aura of his hymn writing.
"Every one of his devotional doses have gone down easy."
We need to read our Bibles as they are to our eyes and seek to consume portions of it into our soul daily. Yet some devotional advice from Bonar can go a long way. He makes you think and play over in detail the Spirit's meaning in the scripture. I have only personal praise and joy in guiding you to this little cluster of gems for your personal devotion.
They come in a series of books taking you through the whole Bible. A text here and there is taken and a devotional thought is brought out in sparkling detail. I propose this, therefore, as an addition to your normal reading and study, but what an addition it could serve to be! Enlighten your soul with some genuine spiritual communion with Christ.
