What is the prayer that changes everything? Praise is the prayer that changes everything. In Stormie's book, The Prayer That Changes Everything, she defines prayer as communicating with God and "praise and worship" as one expression of our love. We become what we worship and by worshipping God we become like Him. Part I of the book addresses 15 reasons to praise God now and Part II of the book speaks of 15 times when praise is crucial. At the conclusion of each chapter are a series of study questions that provide an opportunity for readers to dig a little deeper into Scripure and apply the readings to their personal lives.
