First of all, let’s look at the root word which is used for “fasting.” The Greek word for fasting is nesteia — a compound of ne (a negative prefix) and esthio which means “to eat.” So the basic root meaning of the word simply means “not to eat.”
But what does this “not eating” food mean? Why did people in the Bible “not eat?” We find a clue in Leviticus 16:29. This verse says that fasting is synonymous with “afflicting one’s soul.” We gain some insight here about how the Hebrews viewed fasting. Fasting is more than just “afflicting one’s body”. It is “afflicting one’s soul.” In other words, fasting in the Hebrew mind is something my soul participates in. Fasting is denying my self. It is denying not only my own body, but also my own wants. It is a way of saying that food and my desires are secondary to something else. Fasting is “afflicting one’s soul” — an act of self-denial. But it is not only an act of self-denial and here is where the monks and hermits went wrong.
Biblical fasting is “not eating” with spiritual communication in mind. How do we know this? Because Biblical fasting always occurs together with prayer in the Bible – ALWAYS. You can pray without fasting, but you cannot fast (Biblically speaking) without praying. Biblical fasting is deliberately abstaining from food for a spiritual reason: communication and relationship with the Father.

I am considering joining a national group to fast for 40 days in pray to God to causes a rivival for our country from sexual immorality and violence and endulgence of self pleasure. It has been 40 years since the Hippie Movement which included the sexual revolution; the ME generation and today, 40 years after 1967, it seems our youth and many of their parents, are involved in sinful behavior regularly.
Can we fast as a group (in whatever individual way each person is directed to fast) for a group purpose of speaking to God and for intercession for those in our nation. To cause a change in behavior, to ask God’s mercy and a change of heart of peoples in this country? To ask for direction and more to ask the Holy SPirit and God, to chagne those people who have walked away from HIM or are not connected to God at all?
Your insight is much appreciated. Is this Biblical, to fast a large group for the prayer of change within this great country the USA?
