More than a decade after spotlighting the consequences of negative thinking in her best-selling Battlefield for the Mind, popular Bible teacher and author Joyce Meyer returns to the topic with specific strategies for those caught in the conflict.

Power Thoughts: 12 Strategies to Win the Battle of the Mind (978-0-446-58036-6, $21.99, FaithWords), releasing Sept. 14, presents lessons and insights Meyer has gathered in the years in between, including details of scientific research that underscores how much thoughts can impact physical and mental health.

“The mind is definitely the battle ground where we do war with Satan and his evil, deceptive thoughts,” she writes. “If we do not war against them, they will turn into actions and our lives will be ruined.”

Though developing a positive outlook on problems and challenges may not alter circumstances immediately or directly, it can bring about a brighter attitude that makes it easier to go through tough times and can lead to changes in situations, she says. Forgiveness is also essential, she adds.

While advocating an aggressive approach to one’s thought life, Meyer emphasizes that she does not believe “that we can think into existence anything that we want.” That is humanism, she says, but “simply recognizing the fact that thoughts are powerful is ... quite biblical.”

After reviewing the importance of right—God-centered—thinking, Meyer mixes biblical examples with stories from the business world and her own life—including the hurdle of starting a gym regime at age 64—to illustrate a dozen Power Thought chapters. Each focuses on what Meyer says is a key foundation, such as, “I will not live in fear” and “I am disciplined and self controlled.”

Providing space to answer “Think About It” questions in each section, she encourages readers to work through the chapters a week at a time in a three-month period or a month at a time in the course of a year.
