As of 2015, the Be series by Warren Wendel Wiersbe features over 50 publications, with "Be Successful" as the 51st in 2010. Wiersbe prominently features God and the Bible as central themes in his books, each of which focuses on a specific attribute such as success, loyalty or love.
Wiersbe asks his readers to examine God's role in their lives by choosing an attribute or characteristic that is natural for human beings, and then expanding on it spiritually. In his book "Be Counted", he draws heavily on the Book of Numbers from the Bible to inspire his readers to feel that they are a person of value. "Be Mature" still uses God and spirituality as a backdrop for human interaction, but also focuses on how to become a more responsible and grateful individual.
Like "Be Mature," "Be Skillful" also offers a more practical approach to the worship of God drawing on the Book of Proverbs as a central motif. "Be Hopeful" focuses more directly on spirituality, harmony and faith. Other works in this series include "Be Joyful," "Be Right," "Be Confident," "Be Comforted" and a great deal more. All of these books focus on spirituality and God, and some also offer a practical and day-to-day approach to faith.
