As the apostle Paul boldly preached the word of God, his most receptive audience consisted of the common people. Both Jews and Gentiles were intrigued by his message and desired to hear more. From week to week, the numbers continued to grow. The multitudes simply wanted to hear what this former blasphemer had to say about the faith he had once sought to exterminate. As the fame of Paul’s message increased, so did the opposition from the religious leaders of his day. The success of the gospel message caused many of the Jews to be filled with envy. They began contradicting and blaspheming Paul’s message. When their efforts failed to hinder the message, they stirred up the people in the cities against the truth. These groups began to assault the believers (Acts 17:1-9).
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.
