Fasting, similar to other actions in life, has specific purposes and appointed times. The Bible offers various reasons why people might fast: an immediate need in prayer (2 Samuel 12:16), a need to loosen the bands of wickedness or undo heavy burdens (Isaiah 58:6), during times of elevated conflict or duty in service (Matthew 17:21; Acts 13:3), as a symbol of mourning (2 Samuel 1:12), and as an outward manifestation of true repentance (Jonah 3:5). This list is not exhaustive, but simply demonstrates that God’s people have many good reasons for fasting. Even if none of these circumstances surfaces in our lives, we should fast because we know that the Lord expects us to do so.
As recorded in Zechariah, the people of God came to the Lord desiring to know if they should continue weeping and fasting as they had done for many years. In response, the Lord asked the people if they ever really fasted UNTO Him. In other words, were they fasting for simply prideful reasons, to be seen of men, or really fasting unto the Lord? The motive of fasting is also addressed in Matthew chapter 6. Christians should never fast in order to please men or to draw praise and attention to themselves. Fasting should be a private matter between the believer and the Lord. The benefits gained by fasting are lost when the motives are improper or impure. Those behaving hypocritically will ensure that people know they are fasting, desiring the praise of men; whereas, the truly humble seek only to please the Lord.
Fasting should play a prominent role in the life of a Christian. Just as believers ought to pray, witness, study, and give, we should also fast. In fact, the Lord's words assumed the Christian would fast when He said, “when ye fast” (Matthew 6:16), not IF ye fast. The question was never to be whether or not we would fast, but how we would do so “when” we fast. Fasting was not prominent among the disciples, but the Lord explained that His departure would signify an elevated need for fasting (Mark 2:20). The life of the apostle Paul confirmed this as he said he was “in fastings often” (2 Corinthians 11:27). It was a common practice of Paul’s devotion to the Lord to deprive his flesh of food, drink, and physical pleasures. The Lord not only desired for the early believers to fast, but His people ought to have times of fasting until He returns.
Modern Christianity has been redefining Bible terminology and fasting is no exception. Perhaps this is because Christians want to look spiritual without the necessary dedication. Some claim to be fasting from certain things like caffeine or sugar intake. The Bible does not offer anyone this type of latitude. True biblical fasting involves much more than refraining from some handpicked pleasure. According to our passage, Paul entreated the people to take meat because they had been fasting for two weeks. Esther 4:16 reveals that fasting consists of taking no food or drink. Although some Bible teachers have suggested that fasting means to simply refrain from earthly joys, fasting in the Bible always includes refraining from food or from both food and drink. Even the results of fasting identify that it is associated with depriving the body of food. In Psalm 109:24, David said, “My knees are weak through fasting; and my flesh faileth of fatness.” Foregoing earthly pleasures is a byproduct of fasting, not the sole object.
