One of the best investments you can make is D.A. Carson's two-volume work, For the Love of God: A Daily Companion for Discovering the Riches of God's Word. Each day he wisely and deftly guides readers through a section of the M'Cheyne Reading Plan, highlighting the "big picture," biblical-theological themes.
Here is an excerpt from the preface:
The challenge has become increasingly severe in recent years, owing to several factors. All of us must confront the regular sins of laziness or lack of discipline, sins of the flesh, and of the pride of life. But there are additional pressures. The sheer pace of life affords us many excuses for sacrificing the important on the altar of the urgent. The constant sensory input from all sides is gently addictive— we become used to being entertained and diverted, and it is difficult to carve out the space and silence necessary for serious and thoughtful reading of Scripture. More seriously yet, the rising biblical illiteracy in Western culture means that the Bible is increasingly a closed book, even to many Christians. As the culture drifts away from its former rootedness in a Judeo-Christian understanding of God, history, truth, right and wrong, purpose, judgment, forgiveness, and community, so the Bible seems stranger and stranger. For precisely the same reason, it becomes all the more urgent to read it and reread it, so that at least confessing Christians preserve the heritage and outlook of a mind shaped and informed by holy Scripture.Vol 1: Preface, Introduction, and M'Cheyne Chart of Daily Bible Readings (237K PDF)
This is a book to encourage that end. Devotional guides tend to offer short, personal readings from the Bible, sometimes only a verse or two, followed by several paragraphs of edifying exposition. Doubtless they provide personal help for believers with private needs, fears, and hopes. But they do not provide the framework of what the Bible says—the “plotline” or “story line”—the big picture that makes sense of all the little bits of the Bible. Wrongly used, such devotional guides may ultimately engender the profoundly wrong-headed view that God exists to sort out my problems; they may foster profoundly mistaken interpretations of some Scriptures, simply because the handful of passages they treat are no longer placed within the framework of the big picture, which is gradually fading from view. Only systematic and repeated reading of the whole Bible can meet these challenges.
That is what this book encourages. Here you will find a plan that will help you read through the New Testament and the Psalms twice, and the rest of the Bible once, in the course of a year—or, on a modification of the plan, in the course of two years. Comment is offered for each day, but this book fails utterly in its goal if you read the comment and not the assigned biblical passages.
