I've miscarried twice as many times as I've carried a baby to term. I don't know why my body does this. I've had a battery of tests done, and the results told us nothing. I have no idea how many times I have burst into tears and wailed to the sky "Why?!"
Why do bad things happen to us?
You know, the bad things that are not the natural consequences of choices, but the things that nobody has any control over: poverty, untimely deaths, chronic illness, famine, abuse...
One explanation I've often heard is that we cannot fully appreciate good if we have no bad to compare it to. I think that is part of it. I think that's why we get hangnails or ear infections or bang our funny bones. I think that's why we have disappointments and phobias. It's why some days are diamonds and some days are stones. But I don't think that anyone needs to feel starvation in order to be grateful for food--mere hunger for a few hours or a day can make a person glad of a meal. And I do think I treasure my children a little bit extra because of how difficult it was to get them here, but obviously mothers without angels also love their children very much. Opposition is just a little piece of the answer to this question.
I have come to the conclusion that the primary reason that bad things happen to good people is to make us more patient and compassionate with others.
In my youth I was very judgmental about couples who waited to have kids, because I knew we were supposed to multiply and replenish... now I realize that life is so much more complicated than that, and maybe they had good reason for waiting, and maybe they didn't want to wait but didn't have a choice. In my own case, with all my miscarriages, for the first 2 1/2 years of my marriage an outsider looking in would not have known what I was going through. They would merely have seen someone who wasn't having children. It's not unusual for a couple to wait a few years after marriage to have children. Unless we told someone what was going on, I'm sure that most people assumed our lack of babies was intentional. They had no idea of our pain. Now that I've been on the inside of a situation, I have learned to not judge, but to just love.
Could God stop the bad things? The pain and the sorrow and suffering in the world? I think so. I think He could. But I think He doesn't, so that we'll learn to be compassionate to our brothers and sisters in the world around us.
