Running for God, Daily Devotions for Children and Early Teens by Colin Tinsley and published by Hope for Youth Ministries.
This book has been written as a devotional especially for children and young people. The life of the Lord Jesus Chrisst has been covered in great details from His birth to His death and what it means to us. Every miracles Christ did and parable He told is included in this book.
Following on from Christ, is the life and ministry of the apostle Paul.
The main reason behind this book is that children will find Christ early in their lives and start "running for Him."
