Fasting is not about food. It is about your heart, your relations with God and about freedom. Fasting as a part of religious ceremony has no power. When it is done as some religious routine, it misses out on the most important aspect: spiritual freedom and repentance.
True fasting, pleasant to God is the fasting of heart. You do not just set aside your body to stay away from food. You set aside your heart and time to pray, search your heart and life out and get cleaned and purified. The power of fasting comes not from food or hunger. It comes from finding the revelation from God, learning His will and getting His power to manifest through your life more fully.
In the Scriptures God says that we should tear our hearts, not our clothes, when we cry out to Him. Abstinence from food should not viewed as the essence of fasting. That is not where its power comes from.
The essence of fasting is your faith and open heart before God, it’s your humility and crying out for help. When we acknowledge our own weakness before God, He replaces it with His strength and power.
Prayer suggestion: When fasting, pray to the Lord to show you, where you have hidden offenses or hard feelings against people. His power can set you free from all the bitterness and lead to victory over any circumstance or illness that come against you.
