Lent is still a little over a week away, but our Old Testament lesson is around the idea of fasting. Uniquely unsuited as I am to talk about fasting as the scale is long past a number I don’t like and is heading to don’t make me look at it territory. The idea of fasting has always taken up the same space in my head as how fast can I lose some weight? It’s a two for one deal, right? I lose weight and I get some spiritual rewards.
Even though I have much easier access to calories than the ancient Israelites, that two for one idea seems to be a human universal. The lesson (Isaiah 58:3-9) opens up with God quoting back to Israel their prayers. “Why have we fasted, and you not see? Why have we humbled ourselves, and you take no knowledge of it?” Already in the questions you can discern a dual purpose. The fast is not just a meaningful spiritual practice in itself, nor is it a fulfillment of the law, but it is carried out in order to capture God’s attention or favor. Hey, I fasted, why didn’t you give me some boon?
And God answers them. He calls out the multiplicity of their intentions. They fast, but they backfill the loss of food with some other pleasure. They give up a meal but take a meal from their workers. They cover quarrelling and fighting and injury with sackcloth. I think the modern word for this is virtue signals.
And then God pushes them. “Is such the fast that I choose?…Will you call this a fast, and a day acceptable to the LORD?” The outward signs are there: Humbling oneself, sackcloth and ashes, bowing with a low head. But does God want the outward signs? Does God need the outward signs? If you want God to see, is this what he is looking for?
The answer is of course no. Although Jesus might say something like: you ought to have done justice and mercy without neglecting the outward form (Matthew 23:23). God explains to them what acceptable fasting looks like. “This is the fast that I choose (Isaiah 58:6):” “loose the bonds of wickedness” which I would gloss as free people from Satan’s tyranny, “undo the straps of the yoke” which would be the proclamation of free grace, to “let the oppressed go free.” God has a right to eat from his creation. He made the vineyard or the garden. He has a right to the crop. But the LORD has broken the yoke. He fasts from his return and gives it to us freely. The kingdom is ours, and if the Kingdom is ours, will God not give us bread?
And since we have been given from the LORD’s fast freely, how should we act? “Is it not to share your bread with the hungry?…when you see the naked, to cover them, and not hide from your own flesh?” That last phrase I think captures something about our ways. When we see someone without, not because they are fasting or going without as a means of taming the body but because they just lack, what do we do? We turn away. We deny that this is our brother, our own flesh. We hide ourselves from such because the specter is too grim. It brings up our great fears. And the need makes demands from us. We are much more comfortable play-acting humility and obedience than doing it.
But this is the fasting that God is after. He has given us the largesse of his fast. And we are to share that with our neighbor. This is the fast that the LORD sees. A living out of the grace that we have been given. A love of all God’s creatures. A faith to walk humbly with God. “Then you shall call, and the LORD will answer; you shall cry, and he will say ‘Here I am.’”
