    The Modern 40 Day Fast | Episode 35

    For centuries men and women have stepped away from the table to fast. To pray, to seek something deeper. But what does a 40 day fast look like today? I'm Dr. Sam Sims with Kingdom fasting and in this podcast I invite you to walk with 4 ordinary people on an extraordinary journey. "God has designed your temple to fast and to be healthier especially when you do it for a spiritual reason. He calls us to do this, and He is there to protect you and help your body get through it." In today's episode, we explore how the body responds during fasting even when sickness tries to set in and why a fasted body is often better equipped to fight it off. This episode unpacks the truth that your body is a temple, designed by God with intention, resilience, and purpose, and reminds us that when we fast in obedience and prayer, God hears us, sustains us, and walks with us through the process.
