I'm fairly certain that if a mediocre writer were to exposit five verses at a time of God's Word over the course of a year, he or she would be seen as gifted by association. So, given the fact that Timothy Keller combines this blessed undertaking with his own God-given skill with appropriate self-disclosure as well as the ability to confront and uplift the reader, this is a special book.
SECOND READING: Last year, I appreciated it. This year, I lived it. I like to think I'm cool and objective, but this year, which includes ongoing, unexpected unemployment, I've had appropriate intervals to identify with pleas for forgiveness, pleas for justice, and pleas for forgiveness. If there is a "downside", is that the Scriptures themselves are jumping off the page before I even get to Keller's insights.
THIRD READING: This book, and of course the psalmody it follows scrupulously, offer a slow-motion revolution for the heart. A few verses at a time, Keller and the biblical text seem to address every idol of the heart and to subsume it in corresponding aspects of the character of the Godhead. The sentries who protect what we believe wrongly about the Father, the Son and the Holy Spirit are picked off so quietly in such an unassuming fashion that the reader hardly realizes to what extent the stronghold of the mind has changed hands by the end of the year. If your experience is like mine, reluctance for repetition melts. I'll be embarking on, I think, my fourth journey through this book in 2019.
FOURTH READING: Keller's comments are secondary. They are scaffolding, and I'm sure he would have it so. His is the framing to encourage the contemplation of the Word of God as a daily and delectable habit.
