Paul and Barnabas admonished the heathen to turn from “vanities unto the living God.” One cannot trust in the Lord and simultaneously trust in anything else. In order for an individual to be saved, he must repent of trusting in anything other than the Lord. One aspect of repentance involves ceasing to trust vanity and turning one’s faith toward the living and true God. This saving faith needs to become a living faith following salvation. Believers should consistently turn from “vain thoughts” and love the law of God (Psalm 119:113). They should turn from the vain labours that spend their strength for nought (Isaiah 49:4) and be “steadfast . . . in the work of the Lord” knowing that their “labour is not in vain in the Lord” (1 Corinthians 15:58). Additionally, believers should turn from “vain words” (Ephesians 5:6) and hold “forth the word of life” (Philippians 2:16).
When men follow after vanity, they themselves become vain. An individual must make a conscious decision to turn from walking after the Lord to pursue vanity (Jeremiah 2:5). Those who follow after vanity are void of understanding (Proverbs 12:11) and end up in poverty (Proverbs 28:19), sometimes both spiritually and physically. David expressed his concern in this area when he said, “I have not sat with vain persons” (Psalm 26:4). He knew the danger of following vanity and declared that he refused even to sit with vain persons. In Psalm 119:37, the penman pleaded with the Lord for help in turning away his eyes from beholding vanity. God desires and wills for the saints of God to cease from following after vanity.
The Bible says that vanity is meaningless and empty, yet men love vanity. It fills their imaginations (Psalm 2:1), their thoughts (Psalm 94:11), and their speech (Psalm 144:8, 11). Vanity consumes man so much that he will weary himself for it (Habakkuk 2:13). In comparison to the vanities of this life, most people spend a brief moment in the eternal word of God. Far too many Christians fear to speak God’s righteousness but demonstrate boldness as they speak on behalf of their favorite vanities. As men tend to forget to spend time with the Lord, they spend entire days pondering the vanity to be enjoyed later in the day. Is it any wonder why people need so many “pick-me-up” drinks and drugs as they weary themselves in pursuit of vanity.
The Lord redeemed Israel out of Egypt for the purpose of worshipping Him. Instead of willingly serving Him, the nation of Israel turned to vanities. In doing so, they ignited the fire of God’s anger (Deuteronomy 32:21-22). Ultimately, God chose to provoke Israel to jealousy with a people “which are not a people” – the Gentiles. Since Israel had provoked the Lord to anger with their vanities, He was going to use Gentiles, whom Israel knew to be “not a people,” to provoke Israel to anger. The Lord expects the redeemed to flee vanity and give themselves wholly to His work, worship, and will. The Lord has now redeemed Jew and Gentile “for his name” (Acts 15:14), and He expects the same from each of us.
The book of Ecclesiastes contains documentation of Solomon’s life experiment apart from God. He examined the worth of subjects involving happiness, wealth, labour, and death. Ultimately, he concluded that life “under the sun” (Ecclesiastes 1:14) was vanity. The word vanity means empty or meaningless. Though Solomon wrote extensively concerning vanity, he was not the only person in the Bible to declare the vanity of life. In fact, Solomon’s father David declared that “every man at his best state is altogether vanity” (Psalm 39:5). King David added that if both men of high and low degree were laid in a balance together, they would be “lighter than vanity” (Psalm 62:9). Thus, regardless of worldly accomplishments and accolades, a life void of God remains meaningless.
Most Christians would consider biblical fasting a very unpleasant undertaking. Considering the complexities of the affliction offered by fasting might better help to understand its value. In our passage, the people of God determined to fast so that they might afflict themselves before the Lord. Several other passages discuss this affliction in even more detail. Isaiah 58:3 and 5 describes the affliction as not merely an affliction of the flesh, but also an affliction of the soul. Additionally, we learn that fasting humbles (Psalm 35:13) and chastens (Psalm 69:10) the soul. Fasting involves much more than merely opposition to one’s flesh. Fasting directly afflicts, chastens, and humbles the soul. Perhaps this is why it is so difficult to fast and so beneficial to do so.
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.
