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.
Any person who suggests that Christianity is simply an easy way to avoid the trials of life speaks as a fool or a liar. In actuality, the Christian life involves an ongoing, outward battle along with a constant inner struggle. Perhaps the greater of the two is the struggle which exists within a believer. Part of the Christian (called the new man) wants to do right, while the other part delights in doing wrong and following the old ways (the old man). Faith in God’s word and God’s plan is a primary means of assuring one’s spiritual success. Today’s passage focuses on the absolute necessity for personal faith within the life of a Christian. The book of Hebrews says, “without faith it is impossible to please him [God].” Hence, the Bible repeatedly states that unbelief displeases God. In fact, faith is so crucial to pleasing God that He devoted an entire Bible chapter pointing to the lives of those who exemplified faith. Since God spent the time, space, and effort to chronicle the faith of those of the past, He surely places no less emphasis on the faith of those living today.
