On the second Sunday of each month, we devote our evening assembly
to answering submitted questions by members or guests. If you have
a question you would like covered, you may give it to me
personally, leave it in the box outside my office or e-mail it to
me. In this lesson, we deal with a question I have been holding on
to for some time. What about fasting? Fasting is mentioned about
40 times in the Bible, but does the Bible demand us to fast? If
so, how, when and why? If not, should we fast?
What is fasting?
Fasting is going without a physical desire or need. Most
commonly we view fasting as going without food. Consider II
Samuel 12:16, 21. David fasted, then when he quit, he
started eating. However, I
Corinthians 7:5 demonstrates a sexual fast. Some today
suggest you may have very specific food fasts where you abstain
from specific kinds of food like having a sweets fast or a coke
fast. While that may be good for you, I haven’t seen any
indication in the Bible that anyone fasted by abstaining from a
particular kind of food or drink while continuing to eat and drink
While the word “fast” can refer to any abstinence for
whatever reason, in the Bible, fasting almost always referred to
abstaining from a physical desire or need in order to focus on a
spiritual need or desire.
Consider the passage in I
Corinthians 7:5 where the couple abstains from sexual
relations to devote themselves to prayer. Thus, going a week
without sexual relations is not a Biblical fast. Praying together
instead of having sexual relations is.
Look again at II
Samuel 12:16, 21. David fasted while he pleaded with the
Lord to save his child.
Kings 21:27, Ahab fasted in repentance. So did Saul in Acts
9:9-11. While fasting, Saul was praying.
35:13, David fasted when he prayed for those who were
69:10 and Ezra 8:21 demonstrate fasting was a means of humbling one’s self before
the Lord. The idea being that when we are depriving ourselves of
our wants and needs to focus on God and His will, we are humbling
ourselves before Him.
With that in mind, we are not surprised to find out fasting
was considered a form of worship or at least considered to
correspond with worship—Luke
2:37 and Acts 13:2.
Having said that, we do notice exceptions. There were what
we might consider natural fasts, that is, fasts that didn’t
happen so much because the people decided to fast but simply
because fasting was the natural reaction to what had happened.
Samuel 31:13 and I Chronicles 10:12, the
inhabitants of Jabesh-gilead fasted as they mourned the death of
Saul and Jonathan.
4:3, the Jews fasted in their mourning about the decree
6:18, King Darius fasted the night Daniel was in the lions
These were not necessarily decisions to fast as much as
people lose hunger or are so worried or distracted they either
can’t or don’t eat in moments of great trial and sorrow. This
kind of fast is not necessarily a spiritual activity.
Finally, we must not labor under the delusion that a fast
is only a fast if it lasts a long time. There is no set time for
fasting in the Bible.
Moses and Jesus fasted 40 days (Exodus
34:28; Deuteronomy 9:9; 9:18; Matthew 4:2), however I
believe they had miraculous help over those periods.
The men of Jabesh-gilead fasted for seven days (I
Esther and her people fasted for three days in Esther
4:16, as did Saul in Acts
Samuel 12:16-18, David fasted seven days. However, he
wasn’t fasting for a particular amount of time, he merely fasted
as long as the child lived, seeking the Lord’s favor.
9:3-5, it appears that Ezra fasted for less than one day,
from the moment he heard of the people’s sin to the evening
You may fast for several days, one day or you might fast
through one meal only. If you take time you would have devoted to
eating or some other physical need or desire and instead devote it
to prayer, singing, study or meditation upon God’s word you are
fasting. By the way, it is not a fast to rush to Bible class
instead of eating and then eat after class is over. Fasting is
when you completely replace your time of eating with spiritual
Must we fast?
Despite the number of times fasting is discussed in the
Bible, it is never commanded in either covenant with the possible
exception of Leviticus
16:29, 31; 23:29, 32. Some suggest the afflicting,
humbling or denying of self in these verses refers to fasting
(there is merit to this argument—in Isaiah
58:5, 10 fasting is connected with this term for
affliction or humbling). If that is the case, then there was only
one command to fast and it was only for one day of the year—the
Day of Atonement, that is on the 10th day of the 7th
month. As Jesus is our atonement and we no longer observe this day
of sacrifice, then there is no command for us to fast. I think
this is important to note, especially for those with health
issues. If you’re pregnant, hypoglycemic, diabetic or anemic God
does not command you to fast putting your health in danger.
However, in the New Testament, fasting seems to be
expected. That is, though it was not commanded Jesus simply
presumes His disciples will fast on occasion. Consider Matthew
6:16. Jesus did not say, “If you fast…” but “When
you fast…” This corresponds with “When you pray…” and
“When you give to the needy…” While Jesus was not commanding
His disciples to fast in this passage, He certainly expected us to
fast as part of our natural walk with the Lord just as our walk
with the Lord will naturally lead us to pray and to give to the
needy, if we are able.
Some guidelines for fasting.
According to Joel
2:12-13, fasting is to be a matter of the heart. We can go
through outward motions, but if the heart is not responding to God
in humility, then our fasting is no good.
9:14-17, Jesus demonstrated that fasting was not to be
done ritualistically, but to be done when it was appropriate.
Fasting was not something that would be done in moments of great
joy, but in moments of grief or pleading. The Pharisees did not
grasp this. They fasted twice a week whether they needed to or not
18:12). Fasting was not a reaction to anything for them,
it was merely an action to check off their duty list.
According to Matthew
6:16-18, when we do fast, we are not to go around letting
everyone know. Rather, we dress as usual, pretty up as usual and
act as usual. No one should be able to tell we are fasting except
demonstrates that fasting must be part of a greater life of
serving God. We cannot live however we want for our pleasure and
then believe we will manipulate God to our side by fasting now and
then. Certainly, fasting may some times be a part of our
repentance, however, fasting itself does not somehow cancel out
Times we might fast.
Samuel 31:13; Esther 4:3—we
often fast when we are mourning. This may be a decision, then
again it may just happen naturally.
Kings 21:27; Acts 9:9—as
we repent and mourn our sins, fasting is appropriate. I am not
suggesting if we haven’t fasted, we haven’t repented. However,
how many of us have ever been so devastated by our own sin that
instead of eating we sought God’s forgiveness through
confession, humbling ourselves before the Lord?
Chronicles 20:3; Ezra 8:21-23—when
we want to petition God, we may fast. Have you ever wanted God’s
favor so badly you would pray instead of eat to seek it?
fasted when he prayed for the illnesses of others. We are quick to
let others know we will pray for them. However, has their health
ever been so important to us that we would go without eating in
order to pray for it? Also, keep in mind David is talking about
his enemies here.
Christians were worshipping and fasting. In fact, this looks like
a congregation wide fast. There is no reason given other than they
were worshipping. Have we ever viewed God as so important that
instead of eating we would gather with the saints to worship Him?
I really think this would be tough for us. After all, if a worship
assembly even puts our lunch plans behind by 15 minutes we get
upset. I find it interesting that we like to have breakfast Bible
studies where we meet some place, eat and talk (which is perfectly
lawful), but what would happen if we said we would start having a
meeting for anyone who wanted to come over their lunch hour one
day a week and instead of eating, we would glorify God in songs
and prayers? How many of us would be interested in that?
church in Antioch fasted and prayed as they sent Paul and Barnabas
on their way for their first missionary journey. Is there any part
of the work we are doing that is so important to us that we will
abstain from eating while we pray God’s blessing upon it? What
about our meetings, Fall Focus, VBS? What about praying for the
men we support as we send them our support?
fasted as he appointed elders in ever city. Have we ever viewed
the assignment of roles in the congregation as anything so
important that we would avoid eating in order to pray about it or
meditate on God’s word about it? What about when appointing
elders or deacons? What about when bringing in preachers? What
about appointing teachers? Is any of that important enough to us
that we will miss a meal or more in order to devote ourselves to
I think it is important to notice one reason for which we
never see anyone fasting. I point this out because so often I hear
people say fasting is good for this and yet we never once see
anyone in the Bible fasting for this reason. Fasting is never used
as a means to demonstrate or gain self-control. If you are dealing
with the sin of gluttony, fasting is not your answer. You will not
gain self-control in your eating by skipping meals. In fact, just
skipping meals, as we have already pointed out, is not really
fasting in the Biblical sense. If all you are doing is trying to
demonstrate self-control by fasting, you will merely prepare
yourself for a fit of gluttony the moment your fast is over.
As I pointed out, fasting is not commanded. Please don’t
take this lesson to mean if you have never fasted you are not
serving God. However, I do think we should take it to heart that
Jesus assumed we would fast. Let’s make sure when we fast, we
are doing so in service to God, humbling ourselves before Him,
focusing on the spiritual. It is not enough to merely skip meals,
we must replace them with spiritual work. How many opportunities
we have to fast. How many needs there are for which fasting might
be the appropriate response. Think of it this way—how many of us
have ever skipped a meal because we were working and didn’t have
time? On the other hand, how many of us have ever so devoted
ourselves to spiritual endeavor that we missed our physical needs
or desires? Let us learn to fast but do so appropriately.
