Is not this the fast that I have chosen? to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke? (Isaiah 58:6 KJV biblestudytools.com) Isaiah chapter 58 express to us the purpose of fasting. Fasting is a time that no eating is done. Fasting unto The Lord is not a diet. Fasting unto The Lord is for spiritual renewal. It is a time for seeking The Lord, that we may know Him better. Fasting is a time of consecration (to spend time with GOD, that we may hear from Him; and gain understanding of His Word, His Will, and His Ways). When we have a problem or desire deliverance from a bad habit, we may fast. We may also fast on behalf of others, that they may be loosed from things that bind them. By GOD’s grace, He strengthens us when we fast. Thank GOD for JESUS. Amen.
