How Should We Fast?
Why Should We Fast? listed several OT narrative situations when people responded by fasting. We observed that fasting serves as a means of intensifying our awareness of our dependence on God and intensifying our prayers.
Considering what we see in the experience of Israel when it comes to fasting, we can discern some things that can both encourage us to fast and guide us as we do so.
When and why should we fast? Generally, when we identify a specific need or situation that requires a season of intensity in prayer. For example:
- Whenever you care deeply about a situation that is out of your control. If fasting serves to increase urgency and intensity, what is going on in your life or another person’s life that needs God’s intervention? Maybe a ruptured relationship, maybe the need for protection in the midst of conflict, may in a big decision that must be made when you can’t predict the outcome. We can fast and pray on behalf of someone who gets a bad diagnosis, who has a big job interview or a big test. We could fast and seek God to move in the life of the people on our Top 5 list.
- When you need to go to God in grief, in a season when tragedy has occurred – in your life or someone else’s. In these seasons fasting acknowledges our utter dependence on God for life and acknowledges his will is sovereign and good.
- When you need to confess sin and commit to a life of repenting from sinful actions.
- Whenever you want to intensify the focus of your prayer.
How should we fast? In ways that make it possible for us to feel the physical longing that remind us of our mortality and dependence on God. We can fast privately about personal situations, and we can join in fasting seasons with the church or with other communities of faith (such as our small group). Fasts can be:
- Private, about personal situations.
- Corporate, in response to a call of the leadership of the church or to a group of faithful friends.
- Spontaneous, for a short time, maybe just one meal, as we pray for God to work when we are surprised or overwhelmed.
- Strategic, planned ahead of time and practiced for a specific duration or rhythmic periods. (i.e. One day a week for a month; one evening a week; every morning for 30 days.)
- From food, to be reminded of our spirit need by our physical hunger.
- From habits or cravings, a fast from media, exercise, or work can serve to break patterns of mindless indulgence and replace them with intentional devotion to God.
- With urgency and intensity, utilizing the fasting season to focus our minds and hearts on being in God’s presence.
One thing Jesus makes clear us that fasting should be discrete, in the sense that the point is to intensify our interaction with God, not to make an impression on other people. (Matt. 6)
We can still fast in community, in response to the call of the church, but we need to always remember fasting is just a vehicle, a tool, it is not an objective.
It is important to understand that the practice of fasting does not make a person more “spiritual” or somehow more acceptable to God. The prophets point out that fasting (like any other religious action) in the absence of willing obedience and the pursuit of Godly character in other parts of our lives is a waste of time (Isaiah 58, Jeremiah 14; 36). Fasting can be a productive discipline when it is accompanied by true repentance or desire to turn to God in worship and obedience. When we have pure motives for why we fast we have great freedom to do it in a variety of situations and with different things.
After my survey of the Old Testament narratives about fasting I had a real sense of personal conviction. Partially because I hadn’t ever taken the time to consider what there is to learn from how and when the people of Israel fasted. But also because it made me wonder why I am not more often so broken, desperate, repentant to employ a season of fasting to intensify my prayers for the lost, the sick, the sinning.
But God is gracious, and I have learned, and I will use fasting as a gift God has given to draw me close.
