“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, and it has not only cost us the potency of our prayers and profound benefits to our bodies but has ultimately disconnected us from a practice essential to the faith of the early saints and to our Lord 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 fasting, when accurately and prayerfully practiced,

• engages the soul, serves the spirit, and benefits the body

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

• is the most holistically transformative experience a Christian can undertake

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