“This kind can come out by nothing but prayer and fasting” — Saint Mark 9:29

In Mark 9:14–29, a desperate father brings his tormented son to the disciples—but they cannot cast the spirit out. When Jesus arrives, deliverance comes swiftly. Later, in private, the disciples ask why they failed. His answer is piercing: “This kind can come out by nothing but prayer and fasting.”

The problem was not technique. It was order. Prayer and fasting reorder the heart before they confront the demon. They realign the soul before they address the storm. Fasting dethrones self-reliance. Prayer enthrones dependence. Together, they shift us from noise to surrender, from striving to abiding.

The father in the story models this reordering when he cries, “I believe; help my unbelief!” He brings both faith and weakness. That honesty is itself a form of surrender. We often want power without preparation, authority without intimacy, victory without surrender. But Jesus teaches that some battles are won long before they appear—won in hidden places where appetite is disciplined and the heart is humbled.

As Isaac of Nineveh wrote, “Fasting is the weapon established by God… through it the demons are defeated.” Fasting empties us of ourselves so we may be filled with God. When the heart is reordered through prayer and fasting, faith is strengthened. When faith is strengthened, authority follows. And when authority flows from intimacy with Christ, strongholds fall.

Before confronting what binds others, let God confront what binds us. Victory begins in reordered devotion.
