Two Questions about Fasting

Fasting
Q: Is fasting a command? Since the Bible says "when you fast..." not "if"...

A: No, fasting is not a command in Scripture. However, as the question points out, fasting was an expectation for disciples of Christ.

Fasting from food and other things is not an exclusively Christian activity. Several other religions practice some form of fasting for spiritual purposes. Likewise, some doctors also recognize the purely physical benefits of fasting. Many today (particularly in an affluent nation such as the United States) scoff at the idea of not-eating as being a good option--much less an option that could be good for you!

However, there is a trend in the health and fitness industry called intermittent fasting that is bucking traditional views about nutrition and meal frequency.

When Jesus was teaching His disciples (and the crowd that had gathered) about the Kingdom of God, He assumed that fasting would be a part of their lifestyle.

In the sermon on the mount, recorded in Matthew 5-7, Jesus describes the nature of the kingdom of heaven. Christ describes how "citizens" of the kingdom should live on the earth. In chapter 6, Jesus begins describing activities and values that Christians definitely value. He starts with giving to the poor:

So when you give to the poor... (Mat 6:2, NASB). Jesus assumes that subjects of the kingdom will give to the poor.

He continues, When you pray... (6:5). Jesus assumes that subjects of the kingdom will pray.

He then teaches the disciples to pray, warning them not to pray as the Gentiles do with meaningless repetition. Jesus gives them a model to pray in accordance with the will of our Father (6:7-13).

Then Jesus continues by saying, Whenever you fast... (6:16). Jesus assumes that subjects of the kingdom will fast.

In some circles, fasting is neglected or even frowned upon. But Jesus considered this important spiritual discipline as worthy of being included in His sermon on what a kingdom lifestyle should include along with other essentials such as giving to the poor and praying to our Father!

Since fasting was a normal activity for those to whom He was already speaking, He didn't give them a bunch of guidelines. He did direct them to not fast like the hypocrites. Instead, make sure that they weren't drawing attention to themselves through this discipline. Fasting is not an activity to be done to gain pity from others or to make a show of piety! Fasting, like praying and giving, is to be done for the Lord and in order to advance His kingdom and grow in our relationship and dependence upon Him.

Q: Are there guidelines to fasting as for what duration, how frequently, from what, etc.?

A: Yes and no. (Thanks for clarifying!)

There is no specific passage in the Bible that outlines exactly how to fast on all occasions (that I am aware of). Most of the examples we see in the biblical accounts are individuals or groups who are fasting for various reasons.

For example, we see the sons of Israel fasting out of sorrow (Judges 20:26); fasting due to repentance (1 Sam. 7:6); fasting as an act of mourning (1 Sam. 31:13); fasting in intense times of seeking the Lord (2 Sam. 12:16); and fasting as an act of humility before the Lord to seek His favor (Ezra 8:21), among other examples.

We also see how not to fast. Jesus taught against fasting like the hypocrites, so that everyone knows you are "suffering for the Lord" (Matt. 6:16-18). The Lord speaks through the prophet Isaiah and decries fasting as a merely "religious" activity -- something done merely as an act of obligation and in a ritualistic fashion with no regard to seeking the Lord's will (Isaiah 58).

Through these texts a picture begins to emerge that fasting is meant to humble us before the Lord and to demonstrate our dependence upon Him for sustaining our very existence (Deuteronomy 8:3; John 4:31-34). Fasting, therefore, should never be done as an attempt to manipulate the God of the universe into doing our will. It is an act of humbling ourselves before the Lord in order to seek His will and rely on Him to accomplish His purposes through us for His glory.

In short, fasting should be done as a response to our relationship with the Lord and always at His leading. While fasting from food is the most normal biblical practice, it is possible (and not anti-biblical) that we would abstain (fast) from anything that the Lord leads us to abstain from for a time set by Him.

One final comment: fasting is reserved for activities and things that are not inherently sinful. Eating is a necessity to live but can be abstained from for a time without serious physical repercussions (although there are certainly some health conditions which should be taken into account before engaging in a fast from food). Another example: while it may be permissible to watch television for a Christian, it may be beneficial to fast from such activities for a time to devote yourself to prayer. While fasting is a separate discipline from prayer, the two are often combined together in the Scriptures and there is certainly value in combining these practices in our walk with the living God.

Prayer vs. Petition

Q: What's the difference between prayer and petition? Phil 4:6 for example. A: An excellent word study question! When attempting to study words from the text it is necessary to analyze the word being studied in the original language (in this case Greek) as attempting to look up the words in English will often produce erroneous results. For example, in English the word petition has within its range of meanings things that are certainly not within the scope of meanings for the Greek word (i.e. “a sheet that is signed to demonstrate agreement with some principle or desire for some social action to be taken” is part of the range of “petition” but not of the Greek deesis from which “petition” is translated). The word most commonly translated as “prayer” in our English Bibles is proseuche , which appears 36 times in the New Testament (NT) in one form or another (for the purposes of this study, we are only examining the usage of these words as nouns – the verbal forms will not be

Smoking Hookah

Q: This week a young Christian talked with me about the practice of smoking Hookah. They attend a church [which] is reaching out to the many Indian and Muslims in the surrounding areas. Their church also have several ministries that support missions in India and Arab countries. As they spoke with me they said that many of their Christian friends are smoking the Hookah. They said that they have been told that certain types of Hookah smoking involve no tobacco but are simply flavored water, other types of Hookah smoking do include tobacco but in a ‘more pure’ form than that of cigarettes that have additives. The Christians that they know of who partake in smoking Hookah do not feel that there is anything sinful in this practice and believe that it is just a part of certain cultures as a way to relax and socialize. Apparently during certain celebrations some of these culture groups get together as a family and include smoking the Hookah together as part of the festivities. These Chris

The Sign of Jonah

Q: Jesus Himself states, "For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth." According to John 19:31, it seems as though Jesus died on the "day of preparation" which was immediately followed by the sabbath, and then followed by the first day of the week. This leads us to when Mark 16:2 happened, the ladies went to the tomb "very early on the first day of the week". It was at this time that the empty tomb was discovered. My question is, according to history and maybe even Greek text, is there any explanation as to why Jesus said that He would be in the heart of the earth for three days and three nights when as I am reading the accounts, I am not coming up with three days and three nights? Thank you, as always! A: This question has been raised by many people. Numerous answers have been suggested. The reasons for asking this question are good on

Who the Heck is Melchizedek?

Melchizedek, Priest and King Question – I've read about Melchizedek a number of times but am confused about who he is entirely. Can you let me know about him, I feel like I'm "missing" something? Answer - Join the club! I think this is a question that has been asked almost as long as the scriptures have been in print and distributed for people to read and study. Melchizedek is one of the most mysterious characters to appear in the Old Testament narrative. The Book of Genesis is categorized as a history book. Rightly so. It contains thousands of years of history. From the literal beginning of history to the death of the man whose name was changed to Israel. Among other things, it is a book of lineages and genealogies tracing mankind from the first created man (Adam) to the patriarch of the nation that God chose to be His representatives on earth. So, it is a little surprising that in the middle of this narrative, in the story of the life of Abraham, that a

What is Salvation, Part 4

Q: What is salvation and can you lose it? There's the saying "once saved always saved". Using the scripture that no one is able to snatch them out of the Fathers hand. (John 10:29) but it says in verse 27 My sheep hear my voice, I know them and they follow me. So the no snatching is referring to those who hear and follow, in other words who are obedient to His Word. So, the ones that do not heed the call of the Lord and follow can be snatched? What about sin hardening the heart? (Hebrew 3:13) Shipwrecked faith? (1Tim 1:19) I have heard the saying - "It's not how you start the race but how you finish it." In Hebrew 3:14 For we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end, If you aren't a true follower of Christ then how can you have the strength on your own to even run the race. It is because of Christ and who He transforms you to be that you would even want to
