Chances are you are among the massive majority of Christians who rarely or never fast. It’s not because we haven’t read our Bibles or sat under faithful preaching or heard about the power of fasting, or even that we don’t genuinely want to do it. We just never actually get around to putting down the fork.
Part of it may be that we live in a society in which food is so ubiquitous that we eat not only when we don’t need to, but sometimes even when we don’t want to. We eat to share a meal with others, to build or grow relationships (good reasons), or just as a distraction from responsibility.
And of course, there are our own cravings and aches for comfort that keep us from the discomfort of fasting.
How to Start Fasting
Fasting is hard. It sounds much easier in concept than it proves to be in practice. It can be surprising how on-edge we feel when we miss a meal. Many an idealistic new fast-er has decided to miss a meal and only found our belly drove us to make up for it long before the next mealtime came.
Fasting sounds so simple, and yet the world, our flesh, and the devil conspire to introduce all sorts of complications that keep it from happening. In view of helping you start down the slow path to good fasting, here are six simple pieces of advice. These suggestions might seem pedantic, but the hope is that such basic counsel can serve those who are new at fasting or have never seriously tried it.
1. Start small.
Don’t go from no fasting to attempting a weeklong. Start with one meal; maybe fast one meal a week for several weeks. Then try two meals, and work your way up to a daylong fast. Perhaps eventually try a two-day juice fast.
A juice fast means abstaining from all food and beverage, except for juice and water. Allowing yourself juice provides nutrients and sugar for the body to keep you operating, while also still feeling the effects from going without solid food. It’s not recommended that you abstain from water during a fast of any length.
Fasting isn’t merely an act of self-deprivation, but a spiritual discipline for seeking more of God’s fullness. Which means we should have a plan for what positive pursuit to undertake in the time it normally takes to eat. We spend a good portion of our day with food in front of us. One significant part of fasting is the time it creates for prayer and meditation on God’s word or some act of love for others.
Before diving headlong into a fast, craft a simple plan. Connect it to your purpose for the fast. Each fast should have a specific spiritual purpose. Identify what that is and design a focus to replace the time you would have spent eating. Without a purpose and plan, it’s not Christian fasting; it’s just going hungry.
Fasting is no license to be unloving. It would be sad to lack concern and care for others around us because of this expression of heightened focus on God. Love for God and for neighbor go together. Good fasting mingles horizontal concern with the vertical. If anything, others should even feel more loved and cared for when we’re fasting.
So as you plan your fast, consider how it will affect others. If you have regular lunches with colleagues or dinners with family or roommates, assess how your abstaining will affect them, and let them know ahead of time, instead of just being a no-show, or springing it on them in the moment that you will not be eating.
Also, consider this backdoor inspiration for fasting: If you make a daily or weekly practice of eating with a particular group of friends or family, and those plans are interrupted by someone’s travel or vacation or atypical circumstances, consider that as an opportunity to fast, rather than eating alone.
The typical form of fasting is personal, private, and partial, but we find a variety of forms in the Bible: personal and communal, private and public, congregational and national, regular and occasional, absolute and partial.
In particular, consider fasting together with your family, small group, or church. Do you share together in some special need for God’s wisdom and guidance? Is there an unusual difficulty in the church, or society, for which you need God’s intervention? Do you want to keep the second coming of Christ in view? Plead with special earnestness for God’s help by linking arms with other believers to fast together.
Fasting from food is not necessarily for everyone. Some health conditions keep even the most devout from the traditional course. However, fasting is not limited to abstaining from food. As Martyn Lloyd-Jones said, “Fasting should really be made to include abstinence from anything which is legitimate in and of itself for the sake of some special spiritual purpose.”
If the better part of wisdom for you, in your health condition, is not to go without food, consider fasting from television, computer, social media, or some other regular enjoyment that would bend your heart toward greater enjoyment of Jesus. Paul even talks about married couples fasting from sex “for a limited time, that you may devote yourselves to prayer” (1 Corinthians 7:5).
