Luke 2:36-38 "And there was a prophetess, Anna, the daughter of Phanuel, of the tribe of Asher. She was advanced in years, having lived with her husband seven years from when she was a virgin, 37 and then as a widow until she was eighty-four. She did not depart from the temple, worshiping with fasting and prayer night and day. 38 And coming up at that very hour she began to give thanks to God and to speak of him to all who were waiting for the redemption of Jerusalem."
In fasting you are aiming to "hear" the Holy Spirit in your human spirit, and learning to recognize His voice as you give yourself to prayer, scripture and obedience. You are a soul, containing a human spirit and living in and with a body. As will be explained more below, fasting enables the Christian to get their spirit, soul and body into proper order.
6. Some thoughts on the benefits of fasting
As your stomach growls, you take the time to pray, signalling to God that your are more intrested in feeding on His word and His power than the food your body is craving. A great verse for remembering the rationale for fasting is 1 Corinthians 6:12 "All things are lawful for me, but not all things are profitable. All things are lawful for me, but I will not be mastered by anything."
Fasting enables your soul and body to get in line with the Holy Spirit residing in your human spirit. Your body is the Holy Spirit's temple (1 Corinthians 6) and the soul is the arena wherein you live out your Christian walk in making decisions (will), thinking thoughts (mind) and developing feelings or affections for God (emotions). To get all of that into allignment with what the Lord is saying through His word is one of the chief goals in fasting.
7. Coming out of a fast
As you prepared to go into your fast, there are some things to consider when coming out of one. First of all, if you went one meal or several days, don't suddenly have a huge meal to try to "make up" for all the food you missed. Ease back into the normal eating schedule. Also too remember that in as much as fasting proclaims your dependency upon God more than food, breaking a fast proclaims your dependency upon God in how He supplies your food. Whether going into a fast or coming out of one - the focus is ever to be on the Lord.
I hope some of these practical tips has piqued your interest in this Biblical practice of fasting.
