There are three fasting resources that I would recommend. These resources are good whether or not this is your first time on a prolonged fast or you have been engaging in prolonged fasts for many years.
First, I highly recommend a fasting journal. It is a great way to stay focus during the fast, maximize this time of consecration and seek God’s purpose and plan for your life. Jentezen Franklin has a fasting journal that I really enjoyed using during my 21-day fast a few years back. I use my own journal now but highly recommend this one.
Second, if you want to read more about fasting in the bible, there are two books that I recommend. One is “Fasting for Spiritual Breakthroughs.” It is a guide to nine biblical fasts and shares some important insights on the power of fasting and prayer. The other is “Fasting: Opening the Door to Deeper, More Intimate, More Powerful Relationship with God.”
