Fasting is more than denying ourselves food. It is choosing to act out, by temporarily denying ourselves food, that we do not live by bread alone. We are completely dependent upon God, and we deliberately choose voluntary weakness. We become identifiably humble in the face of the problems with which we are dealing. We admit to each other, and primarily to God: only you can get us through this “mess.”
You want to know what to pass down the line? It is this: your life is not your life. It is Christ’s, and Christ would have you live your life with others in mind.
I often talk about “speaking faith,” which for me means (among other things) giving life to our ideas and beliefs by speaking them aloud. Moving them from the realm of our personal, interior selves to an external realm where they can become infectious and dynamic. That’s the kind of thing I want to happen to my prayers, to my fasting, to whatever self-denial I decide to undertake.
