Why do we fast?

The essential answer is simply “we fast because God has commanded us to fast.” If God asked us to burn sacrifices, we would burn sacrifices. If God asked us to run ten miles at least once a month, we’d all take up running. It’s just what we do.

And yet, obedience without understanding is never the goal. God often teaches us through symbols, and the rituals and ordinances we carry out are often full of them. So, why do we fast? This hymn provides a few suggestions.

[We] pray thy Spirit from above
Will cleanse our hearts, cast out our fear,
And fill our hunger with thy love. (verse 1)

The concept of filling our hunger with His love is an interesting one to me. Fasting definitely introduces a “hole” in us. It not only induces physical weakness, but it often feels as if there’s a pit in our stomach.  The natural man’s remedy to fasting is to fill that hole with food, but God invites us to instead seek to fill it with divine blessings.

Thru this small sacrifice, may we
Recall that strength and life each day
Are sacred blessings sent from thee (verse 2)

Fasting reminds us of our own dependence. Within just a few hours of skipping a meal, we are weak, humbled, and very aware of our own needy-ness. Fasting can serve as a reminder of our own dependence on God, for his blessings and continued sustenance. It can also symbolically remind us of our own spiritual dependence. How much are we spiritually weakened when we go just a day or two without scripture study, or a few hours without prayer?

And may our fast fill us with care
For all thy children now in need. (verse 3)

In our own fast, we are also more able to sympathize with those who are in physical need. Many of God’s children barely have enough to survive. We who have so much, who can skip a couple meals without any lasting consequences—surely fasting reminds us of our responsibility to care for those who fast because they have no choice, or who worry every day how they’ll make ends meet.

This fast, dear Father, sanctify (verse 4)

Because fasting has been commanded by God, obedience brings additional blessings. Our simple choice to obey increases our faith, and gives us access to spiritual blessings God is ready to pour out upon us.  Our fasting can be sanctified, made holy, if we do it in faith. It can bring an added measure of the Spirit, with the accompanying blessings that brings.

There’s a beautiful passage in Isaiah about the power that can accompany a humble and faithful fast. Take some time to really read it:

Is not this the fast that I have chosen? to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke?

Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh?

Then shall thy light break forth as the morning, and thine health shall spring forth speedily: and thy righteousness shall go before thee; the glory of the Lord shall be thy rearward.
(Isaiah 58:6-8)

And then comes verse 9:

Then shalt thou call, and the Lord shall answer; thou shalt cry, and he shall say, Here I am.”

What a beautiful promise.

So next time you’re fasting, make it a true fast, a sanctified one. Seek the blessings God has already promised to those who fast in humility and faith. The blessings are great.
