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.
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.
The Bible always serves as the best source for adequately defining a Bible word. According to Joshua 7:19, confession is connected to the act of telling what a person has done—refusing to keep it hidden. Joshua told Achan to give “glory to the LORD God of Israel, and make confession unto him; and tell me now what thou hast done; hide it not from me.” Psalm 32:5 identifies confession as acknowledging a matter—refusing to hide it. Additionally, Proverbs 28:13 defines confession as the opposite of covering one's sin. In John 1:20, the word confessed appears twice with a defining phrase in between— “and denied not.” In the same manner, Acts 19:18 demonstrates that those who “confessed” “came . . . and shewed their deeds.” The scriptural evidence points to confession as the willingness to make known that which could otherwise be private, personal, or hidden. Keep in mind that regardless of one's willingness to confess, nothing can be hidden from the Lord.
