Great Book for Men’s Group
Format: Hardcover
Our men’s group was looking for a great book to for our mid-week Bible Study and were excited to learn that Max Lucado had this book. God Never Gives Up on You has been perfect. Each chapter is easy to read while providing depth in thought. The best part is that each chapter is only about 10pgs (which seems to be a great number for our group). Great questions for group discussion at the end of the book too!

I enjoyed this book. Jacob was a good study. I learned that God can use me in spite of me.

Much Needed Message
Format: Kindle
Beyond the message, I thoroughly enjoyed the story of Jacob in the Book of Genesis. And I thoroughly enjoyed Pastor Max Lucado‘s take on the story, and how he made it come to life for me.
You will not be disappointed in this book, or it’s message,… I promise.

Very insightful
Format: Paperback
A very interesting way to break down the concepts of basic and/or sophisticated cybersecurity. In that retrospect, you come to see that all security measures are quite the same. The difference lies in the environment; one is a corporate office, the other is Feudal Japan. It's a good read
