Authentic fasting     

Fasting must be accompanied with goodwill and good works toward others to be effective and pleasing to God. 

Scripture Reading

Isaiah 58   

Key passages

Isaiah 58:3-4 — “‘Why have we fasted,’ they say, ‘and you have not seen it? Why have we humbled ourselves, and you have not noticed?’ “Yet on the day of your fasting, you do as you please and exploit all your workers. Your fasting ends in quarreling and strife, and in striking each other with wicked fists. You cannot fast as you do today and expect your voice to be heard on high.” 

Fasting thought

“Why is this fasting unacceptable to God? What’s wrong with it? What’s wrong with it is that it left the sin in their lives untouched. The only authentic fasting is fasting that includes a spiritual attack against our own sin. Whatever else we fast for, we must fast for our own holiness. We cannot fast for anything with authenticity while living in known sin.” - John Piper 


Father in heaven, grant me the faith to move closer to the light of God’s holiness and to deal with the darkness of my own soul. Grant me the courage through this fast to examine my attitudes and behaviors toward those around me and to make right any wrongs for which I am responsible. Father, I desire that my fast be acceptable to you. In Jesus’ name, I pray. Amen. 

Prayer & Fasting Journal

We encourage you to keep a journal to document your thoughts and prayers as God moves during this time of prayer and fasting. You can journal on your smart phone, on paper, or anywhere that will be easily accessed by you and work well as you journey through these 21 days.
