If there is anything that signifies seriousness, it is when you want something so badly that you will stop eating in the pursuit of it, or when the absence of something in your life, or in the church, or in the world grieves you so badly that you give up eating to express your humiliation and your longing to see it come.
The people that God has used to spark revival have often been those of extraordinary seriousness of purpose and much fasting. Jonathan Edwards, who led the Great Awakening 100 years before William Sprague and Francis Wayland reprimanded the ministers of his day like this:
One thing more I would mention concerning fasting and prayer, wherein I think there has been a neglect in ministers; and that is, that although they recommend and much insist on the duty of secret prayer, in their preaching; so little is said about secret fasting. It is a duty recommended by our Saviour to his followers, just in the like manner as secret prayer is; as may be seen by comparing the 5th and 6th vss. of the 6th chapter of Matthew with vss. 16-18. Though I don’t suppose that secret fasting is to be practiced in a stated manner and steady course as secret prayer, yet it seems to me ’tis a duty that all professing Christians should practice, and frequently practice.
Well my guess is that either Jonathan Edwards is wrong or 95% of us are wrong, for I doubt that 5% practice fasting at all, let alone frequently. But if Edwards is right, we are neglecting Christian duty similar to the way we would if we neglected prayer.
