Prayer and Fasting - Required or Recommended?
The Word of God does not specifically command believers to spend time in prayer and fasting. At the same time, prayer and fasting is definitely something we should be doing. Far too often, though, the focus of prayer and fasting is on abstaining from food. Instead, the purpose of Christian fasting should be to take our eyes off the things of this world and focus our thoughts on God. Fasting should always be limited to a set time because not eating for extended periods can be damaging to the body. Fasting is not a method of punishing our bodies and it is not be used as a "dieting method" either. We are not to spend time in prayer and fasting in order to lose weight, but rather to gain a deeper fellowship with God.
By taking our eyes off the things of this world through prayer and biblical fasting, we can focus better on Christ. Matthew 6:16-18 declares, "When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show men they are fasting. I tell you the truth, they have received their reward in full. But when you fast, put oil on your head and wash your face, so that it will not be obvious to men that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you."
