Elkanah had two wives, one named Hannah and the other Peninnah. Peninnah had children, but Hannah remained barren. Peninnah used this opportunity of Hannah’s barren state to provoke her, hoping that she could trouble her rival. The Christian’s primary adversary is much different from Peninnah, but Satan’s goal and resolve is identical to this example. The adversary, the Devil (1 Peter 5:8), wants believers to live troubled, fretful, and defeated lives. If he can cause a believer to fret and to worry and to complain, he has a much greater chance of turning that believer’s heart against the Lord (Proverbs 19:3). The Devil knows that if he turns the heart, he might be able to cause that believer to curse the Lord (Isaiah 8:21). Satan uses worry as one of the foundational elements in his multipronged attack to bring about his greater objective. He wants to turn hearts against God! Those believers who struggle most with worry offer Satan the greatest chance of success
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.
