Should we fast?


by Shawn Brasseaux

“Should we fast in this the Dispensation of Grace? Is fasting encouraged or discouraged in Paul’s epistles?”

Friend, during this the Lenten Season, we are hearing much about fasting. Your question is most definitely pertinent to this time on the religious calendar. Right now, some professing Christians are fasting. Instructed by their denominational hierarchy, they are “doing penances” (suffering for their sins to receive God’s favor). That is, they have temporarily abstained from “guilty pleasures” during Lent, showing “remorse” for overeating and misbehaving on Fat Tuesday (Mardi Gras). They refuse to eat meat on Fridays during Lent. In addition, they deprive themselves of other favorites such as sugary foods, beer, social media, cigarettes, carbonated beverages, profanity, and chocolate.

All the religiosity aside, is fasting necessary for us today? Does God require we Christians fast? What does the Bible say? We will look into the Scriptures for answers. By the way, if you want, friend, you may go immediately to the end of this study for the summary, and then come back to re-read from the beginning. I decided to include all 65 references to fasting in the Scriptures just so we could establish a biblical portrait of what it entails. Fasting is a personal choice, not explicitly commanded in Paul’s epistles (unless in the case of marriage, which we will see later).

The King James Bible makes at least 65 direct references to the practice of fasting (giving up food and/or drink for a time). One thing before we begin looking at all those verses. Please notice how fasting and prayer are often linked together in Scripture. Fasting was a religious duty in Israel, who you will (hopefully) recall was functioning under Old Testament Judaism. You will also see that fasting was often prevalent in times of distress (sadness, depression) and peril (danger). Now, beloved, we get to those verses so the Holy Spirit can enlighten us!

[5] Is it such a fast that I have chosen? a day for a man to afflict his soul? is it to bow down his head as a bulrush, and to spread sackcloth and ashes under him? wilt thou call this a fast, and an acceptable day to the LORD?

So, a quick review of these references…. Of the 65 fasting references in the Bible, only eight are found in Paul’s ministry (five in the Book of Acts, once in 1 Corinthians, and twice in 2 Corinthians). Three of those references in Paul’s ministry apply to church leaders and/or the local church assembly (Acts 13:2; Acts 13:3; 2 Corinthians 6:5). Seven references apply specifically to Paul’s personal fastings (Acts 13:2-3; Acts 14:23; Acts 27:9,33; 2 Corinthians 6:5; 2 Corinthians 11:27). Only one reference is written particularly to individual members of the Church the Body of Christ—namely, married couples (1 Corinthians 7:5).


As mentioned earlier, in Christendom today, we hear so much about fasting—particularly during the time of Lent (40-day period between Mardi Gras/Ash Wednesday and Easter Sunday). With all of that religious talk, you would almost think that it would be a sin for a Christian not to fast. However, there is no explicit command in the Bible that all Christians “must” fast in the Dispensation of Grace. Yes, Paul and his ministry coworkers did it from time to time (Acts 13:2-3; Acts 14:23; 2 Corinthians 6:5; 2 Corinthians 11:27). That fasting, along with prayer, was involved with major ministry undertakings. It was a time of intense preparation and focus.

Most definitely, we can find the Israelites fasting in the Scriptures. Yes, even the Lord Jesus fasted 40 days and 40 nights before He began His earthly ministry (Matthew 4:2;cf. Luke 4:2). However, their program is not our pattern! Just because the Jews did something, we are not necessarily to do it. (Are we going to offer animal sacrifices and kill people who work on the Saturday Sabbath as the Jews did in Scripture TOO?) Saint Paul is our apostle, as he declared by the Holy Spirit: “For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office” (Romans 11:13). Paul is the Lord Jesus Christ’s spokesman to us Gentiles. In that body of Pauline truth—“the Dispensation of the Grace of God” (Ephesians 3:2)—we find God’s instructions to us today. That would be the 13 Bible Books, Romans through Philemon.

The Apostle Paul never tells us that we must fast (no, that would be religion that makes such demands). Saint Paul does instruct that husbands and wives who have agreed not to be intimate for a time, are to “give [themselves] to fasting and prayer” (1 Corinthians 7:5). Why would this be necessary? Remember, the verse continues, “and come together again, that Satan tempt you not for your incontinency [lack of self-control].” One of God’s designs in marriage is to fulfill the natural sexual urge (libido). If sexual intercourse is lacking in the marriage relationship, Satan can eventually use this to his advantage. Those desires, if not satisfied by the spouse, can lead to extramarital affairs. Self-control will be gone. Recall that fasting and prayer were done in Scripture during times of peril (danger) or distress (sadness, depression). A marriage without intimacy is vulnerable to Satan’s attacks, and people physically separated from their spouses are (or at least should be!) missing them. Evidently, prayer and fasting are the means whereby God strengthens (“self-controls”) Christians who cannot be (or have agreed not to be) intimate with their spouses for a specific period. The Pauline doctrine on marriage (1 Corinthians chapter 7) will equip the married saints praying that doctrine. God’s Word will effectually work in them that believe, 1 Thessalonians 2:13 says.

Except if that reference above in 1 Corinthians 7:5 describes our situation, fasting is a personal choice that God will not make for us. Again, there is no direct command in Paul’s epistles not to fast. Save in the case of marriage, there is no direct command to fast in Paul’s epistles. Again, it is a personal choice that you must decide for yourself. Is fasting appropriate for you? Should you choose to go without food for a time, while you are in prayer, in distress, or in depression? (Certainly never deprive yourself of water!) I will not tell you what to do. The Bible does not tell you what to do. If you want to fast, fine. If you do not want to fast, fine as well. BUT, please hear this word of caution.

Matthew 6:16-18, which we saw earlier: “[16] Moreover when ye fast, be not, as the hypocrites, of a sad countenance: for they disfigure their faces, that they may appear unto men to fast. Verily I say unto you, They have their reward. [17] But thou, when thou fastest, anoint thine head, and wash thy face; [18] That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly.”

Do you see how Jesus exposed fasting as the blind ritual that Judaism had made it? Do you see how Jesus wanted His Little Flock to fast without doing it as a “show?” I am afraid that many “Christian” people today have drawn too much attention to themselves because they have “fasted.” Again, they boast about how they have “given up” “worldly pleasures” (certain foods or bad habits, for example) during Lent, the 40 days prior to Easter Sunday. They do “penance,” suffering for their sins. They want to show God “just how ‘sorry’ they are for their sins committed on Fat Tuesday (Mardi Gras)” and “just how ‘dedicated’ they are to living ‘strict, godly’ lives until Easter Sunday.” Of course, some never make it all the way through the 40 days without reverting to their “relinquished pleasure!”

If you noticed in verses we presented earlier, fasting in Judaism eventually became a worthless religious practice. The Lord Jesus lamented that some people no longer fasted in faith. They just did it just to feel religious, stroke their egos, to show off, and to brag to others, “Look at how faithful I am to God! I am so holy and pious because I fast often!” Notice how the Pharisee bragged, “I fast twice in the week, I give tithes of all that I possess” (Luke 18:12). The fasting here was not done in faith. It was just some mindless religious ritual performed so one could then boast of his “faithfulness” and his “holiness.” We want to avoid this should we choose to fast.
