Fasting is a tremendous practice. It has helped me pursue sexual purity. When I fast, I no longer have a desire to view pornography and masturbate or to experiment with drugs, get drunk, fornicate with a woman I barely know, or any other sinful thing. I believe that fasting is a gift from God. Not all fasts are valid, though. Jesus said, in Matthew 6, to not be like the religious hypocrites. Don’t show off-- do it for the glory of God.
Right now I’m on my fourth day of caffeine fasting. The Lord put it on my heart to fast from caffeine. I suffered a headache yesterday; it’s a withdrawal symptom. The good thing about fasting is that you can pretty much make your own rules. You can fast from almost anything, like alcohol, video games, cigarettes, swearing, food, drinks, sex, fast food, coffee, etc.
When you fast, you are basically saying to God that fellowship with Him is more important than eating and drinking. Fasting is a spiritual act-- it’s much more than abstaining from food and drinks, It’s a form of worship that helps us understand that faith is more important than filling our bellies.
