The Bible has many examples of reputations that were changed. For instance, Moses grew up in Egypt, specifically in the house of Pharaoh. One day, when he was a grown man, he witnessed an Egyptian smiting a Jew. Moses killed the Egyptian in order to protect his kinsman. Bad news travels fast and Moses immediately developed a reputation as a short-tempered killer. He learned of this when he attempted to intervene during a dispute between two Hebrews. After the Pharaoh found out Moses’ identity, Moses ran for his life and spent the next forty years in hiding. Eventually, the Lord spoke to Moses and called him to lead the Israelites out of Egypt and into a land of promise. Moses failed to lead the people into Canaan, but he succeeded in changing his tarnished reputation into something that God commended (Numbers 12:3).
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.
