Fasting is a bodily act which comprises of great spiritual benefit. From the old testament to the new, fasting is regarded as the default of a spiritual person. Jesus fasted, Isaiah fasted, the whole Israel fasted on some occasions. What exactly is the kind of fasting God requires? Is it simply a denial of food intake and a plea that God will move faster in answering our prayers? The people in Isaiah's time had that idea and Prophet Isaiah had to pen these phases: ISA 58:6-11 KJV Is not this the fast that I have chosen? to lose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke? Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh? Then shall thy light break forth as the morning, and thine health shall spring forth speedily: and thy righteousness shall go before thee; the glory of the Lord shall be thy reward. Then shalt thou call, and the Lord shall answer; thou shalt cry, and he shall say, Here I am. If thou take away from the midst of thee the yoke, the putting forth of the finger, and speaking vanity; And if thou draw out thy soul to the hungry, and satisfy the afflicted soul; then shall thy light rise in obscurity, and thy darkness be as the noonday: And the Lord shall guide thee continually, and satisfy thy soul in drought, and make fat thy bones: and thou shalt be like a watered garden, and like a spring of water, whose waters fail not. Fasting denies food to ourselves but brought forth release to others. That kind of fast is what God desires.
