Missionary Sarah Young’s Jesus Calling devotional (Thomas Nelson) has now sold more than 2.5 million units worldwide, and Gary Chapman and Ross Campbell’s The 5 Love Languages of Children (Northfield Publishing/Moody Publishers) has exceeded 1 million copies sold.

In addition, the Jesus Calling brand of titles, including Jesus Calling for Kids and the Jesus Calling Devotional Bible, has sold more than 3.5 million units, reported Thomas Nelson.

“What an honor it is to watch God at work, drawing people closer to Him through the pages of this book,” said Laura Minchew, senior vice president of specialty publishing at Thomas Nelson. “I heard a recent story of a woman so touched by Jesus Calling that she purchased 23 copies to give to every member in her family.”

Jesus Calling is also now available in a large deluxe edition that features large, black print and the scriptures written out after each devotional entry. The book was also released as an app in 2011, giving readers access to the full-text book with the ability to share quotations or gift the app to friends.

Young’s next devotional, Jesus Today: Experience Hope Through His Presence, is scheduled to release in the fall.
