We were created to worship. Our problem is that we choose not to worship God. While thats definitely a problem for everybody, its especially a problem for believers, who call themselves by the name of Christ. Of all people, we ought not to be caught worshiping anything or anyone else! This little book (122 pages, including discussion questions and citations) packs a wallop as it directs our eyes away from man-centered definitions of worship, instead asking us to consider how God defines worship. And its not wholly related to our music.Does music play a part? Sure, because music in most Sunday morning services is designed to help us stop thinking about ourselves (usually), and fix our eyes on Jesus, the Author and Perfecter of faith. But we cant live unGodly lives during the week and expect our words on Sunday mornings to please God. The mouth speaks out of that which fills the heart, says Matt. 12:34, and if the meditations of our heart are unacceptable to Him, the words coming out of our mouths are only lies.But Giglio doesnt leave us there. He moves us from being aware of the problem to being part of the solution. We must change our minds about what worship is, and learn how to work with God to topple those idols, exchanging worship of a lie for worshiping in spirit and truth. A hint: its not about what you say. Its about what you do. Not just on Sunday mornings, but all week long.Obviously, worship is a topic that needs more than 100 pages to work through, especially because its the primary task to which God has called all His saints. But with the profusion of idols in every heart, the task of being conformed to the image of the Son can seem daunting; we dont know even how to begin. Louie Giglio has written a little book, but this little book can go a long way to help us renew our minds as we cooperate with the Spirit of God to renovate the throne-rooms of our hearts.
