In fact, one of the frustrations of these days has been precisely the sense of limitation. I've only been to Mass three times since this kicked in. I'm pushing it to do anything at the computer, so my various projects are on hold, except for the ones I have figured out how to carry forward in ten-minute intervals on my feet, or while flat on my back--and that doesn't work very well, to tell the truth. I had to cancel plans to offer a book display of Theology of the Body materials for tomorrow's conference on Protecting Families from Pornography because--not only can I not carry the boxes of books (someone might offer to help with that part), I can't stand for long periods of time. Not that I could manage the long drive to the Green Bay area. "Offer it up!"
God is "offering" something, too: to work more with my inability than with my abilities.
And there's the rub: I would really rather God use my talents. And why? Partly because of the sense of satisfaction that offers me--but I have to admit there's something more than just that honest and appropriate enjoyment of the exercise of a gift God must also delight in... I also want something to point to; some "trace" or record of my achievements. Something I can look back on for reassurance that my life is meaningful, or that I am making some sort of worthwhile contribution to my community. And that's just not there when God chooses to use a backache to carry out His work!
On the other hand, if God chooses to use my inability, and in fact uses it to work outsized marvels of his mercy for someone I may not meet this side of eternity, that means I will never be out of work! I will always be able to cooperate with God, and on a vaster scale than my "abilities" would ever reach.
