3. Tell Only the People You Must
Your spouse will need to know you are fasting.
Beyond that, you would be better off not telling many people that you are fasting. Most won’t understand.
Fasting can also become a source of pride and boasting as you spread the news to more and more people.
Telling your pastor can be a help both to you and to him. It will be an encouragement for him to pray more specifically for you during this time. And you will know that someone is praying for your spiritual and physical well being.
