“At last! An accessible yet inspirational introduction to one of the most powerful, countercultural, and neglected aspects of prayer.”—Pete Greig, founder of 24-7 Prayer and author of How to Pray: A Simple Guide for Normal People

We’ve forgotten how to fast. This loss has cost us not only the potency of our prayers and benefits to our bodies, but has ultimately disconnected us from Jesus Himself. While fasting is often dismissed as just another diet trend, Pastor Reward Sibanda clarifies what true spiritual fasting is—and what it is not. He explains why we should fast and how to biblically fast so we can experience deeper communion with God.

Sibanda draws from his own twenty-one-day fasting experiences, engaging anecdotes, Scripture, and scientific insights to reveal how this prayerful practice

• enriches our faith by realigning our bodies, spirits, and souls

• expands our understanding of what’s possible when we surrender our whole selves to God

• resets our biological rhythms and increases our physical well-being, even to the cellular level

Whether you’re new to fasting or a seasoned practitioner, this book—which includes a daily guide—provides invaluable insights that will renew your relationship with God and yourself. Discover for yourself this life-changing gift!
