21 Days of Transforming Prayer by Daniel Henderson (2021)

I don’t recall how I came about this book, but I re-discovered it in my Kindle precisely when I needed it most. Despite all the changes happening in my life, I take too little time to pray, and the results of my self-dependence have been frustration and spiritual discouragement.

Do you ever face times like these? By God’s grace, right in the midst of my constant and consistent failure, I picked up this book and read this important reminder from the Introduction:

I’ve discovered that most Christians are secretly discouraged with prayer. We look around the church and assume everyone else must be praying more and better than we are. With rare exception, they are not. (10)

I’m not alone! Every Christian apparently faces these seasons of faulty, weak, or non-existent prayer—and thank God, it’s a symptom of a curable disease! The disease is selfishness and the cure is worship—seeking God’s face through the Word and through prayer.

Brief Summary of 21 Days of Transforming Prayer

Apparently this book is a shortened, devotional version of Daniel Henderson’s larger study, Transforming Prayer: How Everything Changes When You Seek God’s Face. I’ve not read that book, but feel like this devotional fed me enough morsels of biblical truth to get my focus back on track.

Through this three-week study, Henderson hopes to rewire our thinking against bad ideas of prayer (i.e. as grocery lists on Day 1 or with impure motives and ineffective methods on Day 15). Instead, he writes to help us grow our prayers naturally through meeting God in the pages of Scripture.

Henderson’s key takeaway from the book is to allow our prayers to flow through four stages as we see God’s character revealed in Scripture. Each time we see as aspect of God’s character, Henderson recommends we respond in prayer by directing our eyes:

  • Upward (Reverence), then
  • Downward (Response), then
  • Inward (Requests), then
  • Outward (Readiness), and back
  • Upward to God in the Word to start it all over again (Day 16).

Through this method of first hearing God speak through His Word and then responding through prayer, we engage in a dialogue with Him that focuses on His glory and our dependence. It’s a reminder to me of what’s been lacking in my own prayer life, because I’ve been so focused on lists that I’ve essentially forgotten even to Whom I’m praying!

Lessons Learned

This book really hit me where I needed it, and from three different angles: as a father and example to my kids, as someone desiring a change of circumstances not Self, and as someone who doesn’t involve enough Bible in my prayers. I’ll touch on each here briefly

I’m a Father and Example to My Kids

The first major lesson I learned from this book is that my kids are learning to pray from nowhere else by my own lips. That’s a troubling realization, especially when I find that during many of our family devotions in the evenings, I ignore what we’ve read in the Word and just dive in immediately to my prayer requests for the day! Henderson writes exactly what I need to remember:

People do not arrive at a new, powerful, and life-changing place in their prayer life through information. It happens more by “infection.” It is not accomplished through explanation but by experience. (23)

He later develops this idea further by writing:

Many believers struggle in learning how to pray. Hundreds of volumes have been written over the centuries on the theology and practice of prayer. Yet the most fundamental principle has often been neglected. Young Christians must learn to pray in community with mature believers.” (90-91)

I’ve Been Desiring Changes in My Circumstances, Not in Myself

A second huge lesson I learned is that my prayers often desire safe trips, healthy bodies, and good days. My prayers don’t at all resemble those of Scripture. As Henderson writes on Day 8:

A summary review of Paul’s specific personal prayer requests reveals a consistent focus on the advancement of the Gospel message, the fulfillment of the mission, and the ultimate glory of God in all things… / Perhaps the fundamental difference between our prayer lists and the prayer concerns we find in the Bible is that we pray about personal problems, while most of the Biblical prayers focus on Christ’s purposes. (44)

He builds on this idea on Day 15 when he encourages:

Pray that God would change you, NOT simply change things. (72)

I Don’t Pray the Word Nearly Enough

A third major lesson came on Day 11, where I realized: “OK, this is exactly what I needed to read.” Henderson opens the discussion about praying with an open Bible with this poignant thought:

It is so easy in our perfunctory approach to prayer to blow into God’s Presence, conduct our daily data dump to be relieved of our worries but not revived in our worship. (53)

Then, based on the “abide” passage of John 15:7-8, he writes this:

If prayer is about my heart becoming intimate and aligned with the heart of the Savior, then I should let Him start the conversation. This is the reality of abiding in Him and letting His words abide in us. (55)

One Critique of the Book

I understand the desire to get this message out in more ways than merely the thick book most people won’t read, so this smaller devotional idea makes sense. I don’t get, however, why it’s broken down in 21 days and why each day doesn’t include a challenge or application. Some days are just introductions to the ones that follow, making it a pretty spotty devotional.

Truth be told, I read the whole thing through in one sitting, as if it were a book with 21 small chapters rather than 21 daily devotionals. I gained way more in one sitting than I would have had I taken the book one day at a time. If the publishers ever rethink this book, they’d do well to offer daily passages for readers to pray through and applications for them to employ.

Conclusion

This book might not include new information for most long-term Christians, but it was short and pithy enough to serve as the exact kind of reminder I needed today. It’s like a bellows to my embers, breathing new passion back into my prayer life.

If you’re a reader, you may get more from Henderson’s larger book, but I was happy with this devotional overview. It’s helped recenter my focus like Psalm 27:8 describes:

When You said, “Seek my face,” my heart said to You, “Your face, Lord, I will seek.”
