Grammy winner and world-renowned worship leader Chris Tomlin and Senior Pastor of Nashville's Church of the City, Darren Whitehead, have partnered to release a new book Oct. 10, Holy Roar: 7 Words that will Change the Way You Worship.

Asking reader's the question, "What does it mean to praise God?," Whitehead explains how the words from thousands of years ago can help us all grow in how we worship today.

"In the ancient world, something extraordinary would happen when God's people would gather to worship Him," he says. "It was more than just singing; it was a declaration, a proclamation, a time to fully embody praise to God for who He is, and what He has done."

Whitehead continues, "In fact, in the Psalms, there are seven Hebrew words that are translated into the English word 'praise,' each of which represents a different aspect of what it means to truly praise God."

In Holy Roar, Tomlin and Whitehead share a fresh perspective from the worship practices of the ancient world. The book aims to grow readers in their understanding of praise as Whitehead offers unique insights, and be inspired as Tomlin shares how those insights take shape in the stories behind favorite worship songs, including "How Great is Our God," "We Fall Down" and "Good Good Father."

"One Sunday morning, Darren shared a message that transformed and deepened my understanding of praise and worship, changing the way I led worship from that day forward," recalls Tomlin. "There was a palpable difference in the congregation's expression of worship after Darren's message, and it made the experience all the more overwhelming."

Tomlin adds, "I kept thinking to myself, 'how have I been a part of writing and leading songs of worship and praise, and I am just now hearing this?' I am so honored to come alongside and share stories of how some of the songs I've been a part of relate with each of these seven words."
