Isaiah asks, “What good is fasting when you keep on fighting and quarreling? This kind of fasting will never get you anywhere with me. You humble yourselves by going through the motions of penance, bowing your heads like reeds bending in the wind. You dress in burlap and cover yourselves with ashes. Is this what you call fasting? Do you really think this will please the LORD?” (Isaiah 58:4-5 NLT) Fasting is a voluntarily abstaining from food for spiritual purposes. The main thing is to present yourself to the Lord as a living sacrifice with a sincere heart. Listen to His instructions. Follow His guidance. He can re-purpose your life, and shift you to another level in your walk with Him.
