The Christian life should be all about discovering and doing what Jesus had said. That's why author Steven K. Scott compiled all that Jesus had said and placed them into different categories, so that we as followers can quickly go into the topic and see what Jesus had commanded us to do about it.
Personally, in his own life, Steven had also turned to this book for help. When his son was 20 years old, he received news that his son needs to go into emergency surgery as he had cancer. It was life-threatening. Steven was in a hotel room and sobbed when he heard that. Then the Holy Spirit directed him to his own book to look into the section about 'Anxiety, worry and fear'.
There, Steven found the comfort and peace he needed. It was not about his son. It is about God.
