God uses fasting to align ourselves to His purposes. Many times we fast out of want, which leads to desperation, but lasting results come from a desperation which leads to a desire for God. Through scripture we will learn about three types of fasts — for people who are looking to be called in to the ministry God has for them, for those who know their calling but are in the place of waiting for God's direction, and for those who are in their ministry but wanting advancement in effectiveness of ministry.
