  • Praying the Bible

Perfect for you if...

  • You struggle with saying things you regret, whether in anger, gossip, or careless moments, and want practical Scripture-based tools to change the pattern.
  • You're already a believer looking to deepen your faith through a structured devotional rather than casual reading.
  • You appreciate accountability and reflection, and you're willing to do daily work (not just passive inspiration) to transform how you communicate.

Maybe not for you if...

  • You're looking for a quick fix rather than a 40-day commitment that requires daily reflection and action.
  • You prefer devotionals without Scripture focus or those that don't tie faith directly to everyday behaviour.
  • You're sceptical of self-help framed through Christianity or want advice grounded in psychology rather than biblical teaching.

About this book

Zip It is a forty-day devotional that expands on the New York Times bestseller Keep It Shut, examining biblical guidance about the tongue and speech. It provides practical instruction on using words to build, bless, encourage, and praise. The devotional addresses the power of words spoken, typed, and texted daily. Scripture contains over 3,500 verses about the tongue's power, reflecting how words can convey love and life or cause discouragement and defeat. Over forty days, this book guides readers in choosing and using words wisely to prevent regret and relationship damage. Each of the forty interactive entries includes a Scripture focus, a story or teaching point, and reflection questions. Entries conclude with an action step tied to the day's verse and a prayer prompt. The entries build progressively, providing tools for effective word use. The devotional challenges readers to use speech for godly purposes: to build rather than break, bless rather than badger, encourage rather than embitter, and praise rather than pounce.
