My knees are weak through fasting, And my flesh is feeble from lack of fatness. Psalms 109:24
“When you fast, your body eliminates toxins from your system. This is called detoxification. When it happens, it can cause mild discomfort such as headaches and irritability during withdrawal from caffeine, sugars and carbs. And naturally, you will have hunger pangs. Avoiding water can make you feel even hungrier, since water helps increase satiety. If you don’t eat food or drink water, your body begins to crave fuel. You’ll likely feel fatigued, dizzy, and weak. David said of his fasting: “My knees are weak through fasting, and my flesh is feeble from lack of fatness” (Psalms 109:24). You may also feel more irritable when you fast. As the hunger builds up, you’re bound to feel cranky. Therefore, mood swings are pretty common. And, when you’re tired and hungry, it can be difficult to concentrate at school or work.”

There’s a lot going on spiritually and physically with fasting.
I would liken it to weaning yourself off relying on the things of the world to sustain you and connecting to God who supplies limitless strengthen and supply for your generous living. I am serious about this. I want everyone to fast.
You detox spiritually and physically.
It may seem difficult physically but the gain is unfathomable. Fast for me and with me as I change out my suitcase and pivot to Seoul, South Korea from 25-31 October 2025 to speak at the World Evangelical Alliance Global Assembly.
I am thankful to have shifted from President & CEO to Founder so I can give this service my complete focus and not have the responsibilities of managing a staff of 20 people in 20 countries at the same time.
Letting go of good things opens our hands to receive the best things.
But there are real implications to our bodies when we do this. It’s not for the weak and faint of heart. But it does represent one of the secrets to David’s deep relationship with God. What about yours?
