I’m a connoisseur of the esoteric, whether in scripture or desserts. Isaiah’s air of mystery reaches through the ages to draw me in and compels me to uncover his ancient mysteries. While design is my calling, occasionally I lend my words to


  1. I love fasting! Are there negative consequences for not fasting? Or is the negative more just a lack of blessings?

  2. Isaiah 58 gives profound promises of fasting. We are here to follow the example of Jesus, especially to sacrifice for others and with our heart with real intent, and then bless another’s life as a result of our fasting (e.g. helping the poor). Those who fast are promised thus:

    6 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?
    7 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?
    8 ¶ 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 crearward.
    9 Then shalt thou acall, 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;
    10 And if thou draw out thy soul to the hungry, and satisfy the afflicted soul; then shall thy light brise in obscurity, and thy darkness be as the noonday:
    11 And the Lord shall guide thee continually, and satisfy thy soul in drought, and cmake fat thy bones: and thou shalt be like a watered garden, and like a spring of water, whose waters fail not.
    12 And they that shall be of thee shall build the old waste places: thou shalt raise up the foundations of many generations; and thou shalt be called, The repairer of the breach, The restorer of paths to dwell in.”

      Thanks for your thoughts on this. I have felt strongly for years that one I should fast for others and two do my best to feed the poor with more than just the cost of two meals

  3. In my younger days I fasted every fast Sunday, for others in need, and when I needed special blessings dealing with home or Church callings. Fasting is going for 24 hrs (or longer if necessary) without food or drink & has to be accompanied with prayer and on Fast Sunday, with a generous Fast Offering.
    I am now 84 years old and have Parkinsons Desease. Because of the medication I have to take I am unable to fast completely but I eat sparingly and still give a generous Fast. I pray I will still continue to receive the blessings Isaiah talks about.

    • Thanks for sharing and still trying. My wife has an ailment that keeps her from fasting too, but she tries and I am fastidious about the practice. Today I am fasting to overcome a weakness of mine.

  4. […] yourself and others to receive God’s blessings.”1 In Isaiah 58, the prophet lists at least eight reasons for fasting, some of which include calling on the Lord, “dealing thy bread to the hungry, […]

  5. Not many Christians Fast and understand the wonderful blessings associated. I really appreciate this post and the highlighted benfits of Fasting. It has helped me to Fast with greater conviction.

  6. A whole new lady

    I have a tender place in my heart for fasting. Three years ago, both my mother and I were diagnosed with a dreaded condition that strikes fear into the heart. Just prior to my diagnosis, The Lord led me through some big decisions. I did an extended fast for help. During this, I received many magnificently simple/clear answers and learned to recognize the voice of the spirit. My healing time was one where my heart was drawn out in constant prayer. Fasting brought me closer to heaven and gave me the peace and healing I needed. I experienced my greatest joys while fasting, and it became so much easier as I prayed for help to fast. (Literally, this has given me strength, and has made my fasting sweet as Ive felt so supported.) My health did spring back, and I grew so much during that time. I’m learning to keep my focus now that I’m healthy. I’m forever grateful for My Father In Heaven and for the Healing power of Christ’s atonement.

  7. I have fasted once a month most of my life… I enjoy good health, the Lord is there for me, and I feel very blessed! It was difficult when I started… used to get headaches; but it was always fruitful with the Holy Spirit and well worth it! I dedicate my fast first and drink lots of water when I’m finished.

    • So glad you have seen these blessings in your life Joan, have you seen any of the other blessings as well?

  8. If you fast from food, but drink water, is it still a fast?

    • That indeed can be a form of fasting! And actually necessary if you want to do any form of extended fasting.

  9. Thank you so much for your reply. I feel much encouraged.
