A Fast Message From God

Is. 58:6-8

I. Definition of Fasting

Fasting=a voluntary withdrawing from food and/or drink, or other fleshly appetite, for a specified period of time.

3 most basic types of fasting mentioned in the Bible:

A. Normal fast [food]

Jesus began His earthly ministry w/ prayer and fasting.

Mt. 4:1-2—a 40 day fast Jesus completed!

Jesus taught His disciples to fast

Mt. 6:16

16 Moreover when (not if) ye fast, be not, as the hypocrites, of a sad countenance…

Though fasting is never commanded, Jesus assumed that the disciples would want to in order to see great things happen!

But it’s not something a Christian has to do, but can choose to do…not many guidelines given in scripture about fasting, either!

Normal fast is no food, only liquids like water, juice, etc…it can last for 1 day (Judges 20:26—1 day fast)

That’s a good place to start!

3 day fast (Paul did this right after getting saved)

40 day fast (several examples in Bible)

Several men alive today who have done 40 day fasts and would say it was absolutely life-changing! (still took in liquids, of course!) [Bill Bright, founder of Campus Crusade for Christ, 1994/James Dobson, Focus on the Family/Jerry Falwell/others]

B. Partial fast

Good if you have diabetes, hypoglycemia, or some other condition which precludes a normal fast.

In the partial fast you omit certain foods for a while, but not others.

Dan. 1—he and 3 Hebrew children did a partial fast, and at the end were stronger and healthier than those eating what they wanted.

Elijah did this on 2 occasions/John Wesley was well known for going days on end eating only bread and water/some give up meats for a time, eating only vegetables/just skipping a meal to spend time in prayer would be another example of a partial fast, or not indulging in things you like as much as just “getting by” w/ something basic, bland. [Giving up flesh’s desires to concentrate on the Spirit!]

C. The absolute fast

Moses went on this kind for 40 days, nothing enters your mouth at all…can be done for a very short time…consult a dr.!

This is the first mention of a fast in scripture -- Ex. 34:28

(law of 1st mention)

27 And the LORD said unto Moses, Write thou these words: for after the tenor of these words I have made a covenant with thee and with Israel.

28 And he was there with the LORD forty days and forty nights; he did neither eat bread, nor drink water. And he wrote upon the tables the words of the covenant, the ten commandments.

When Moses received the 10 commandments from God, he engaged in a 40 day fast.

You may have noticed it said he didn’t eat OR drink…don’t anybody go out of here and try that! That is a human impossibility apart from divine intervention…some have worked up to a 40 day fast from food, but no one could survive 40 days w/ no drink…this was a miracle!

II. Purpose of fasting

A way to seek God by denying the physical in order to focus on the spiritual…

…for this reason prayer and fasting must always go together (or it does you no good spiritually!)
