I bought two of these devotionals as Christmas presents for my younger brothers who are 10, and 12 respectively. I bought the corresponding Bible for my 10 year old brother, and I bought the NIV Revolution Bible for the 12 year old. As soon as I browsed through the pages, I loved it. The Devotional is prescribed for "boys" but this can adequately serve a young man up until 15. Each devotional uses scriptural lessons to provide young men with great values that should encourage them to be Stronger, Smarter, Deeper, and Cooler in Christ.
The devotional is written in black and white (a turn off to some young boys), however, it is laid out in a format that is easy to understand and follow e.g. Day 1, Day 2, Day3..., etc. This is a great way to give your young man an independent approach to studying the Word of God. It is also a tool that can be used for family devotions. It will aid parents in starting discussions that would be otherwise difficult to start.
I would recommend this devotional for any young man between the ages of 10 and 15. For the older boys (especially if you have a young man who does not enjoy reading), this might be better suited to them than a devotional that is prescribed for their age range. The content is not "babyish", yet it is presented in a simple straight forward way. I am a young woman, and even though the devotion is prescribed for young men, I was able to take take some valuable lessons from this, and glean certain portions of scripture in a new light. It is certainly a way to keep the Word of God, alive and current for your young man.
