 If you want to have an effective fast, remember this advice. Jesus said, And when you fast, don't make it obvious as the hypocrites do, for they try to look miserable and to shelve so people will admire them for their fasting. I tell you the truth, that is the only reward they'll ever get. When you fast, comb your hair, wash your face, then no one will notice that you are fasting except your father who knows what you do in private. And your father who sees everything will reward you. That's Matthew 6, 16 to 18. First, notice that Jesus said when you fast. This implies that we ought to do so regularly. Secondly, we are instructed to fast privately. Now it's not like fasting loses its power should someone find out you're fasting. This has to do with motive. Finally, fast prayerfully. Fasting must be paired with prayer. A fast without prayer is just a diet. Fasting is about disconnecting from the flesh and the desires of this world and focusing on and relying upon the Lord.
