It seems that we're all to ready to answer someone who's sharing her misgivings about her life with meaningless babble instead of recognizing her burdens as they are- the weight of sin upon her- and giving her the reassurance that can only come from the cross. Whether she's wondering if she'll ever marry, be blessed with another child (or a child), if she'll ever get a good night's sleep, or whether she'll feel confident about the decisions she's made as a mother or wife, the correct answer is not, "Oh, it will happen." Or even, "Give it time." It's most definitely not, "It will happen when you least expect it."
Unless, of course, you've had some dream or vision that you are certain is from God himself that sheds light on the future of the woman, and you have been given clear revelation about the meaning of said dream or vision. If that's the case, then, by all means, lead the woman to believe that her trial is going to be over soon. But if you're like the rest of us, who flounder through life without the vision and dreams, then please, point her instead to the only things that can be guaranteed: that Christ loves her, and shed his blood for her, and will come again to redeem this world and everything in it, including her; and until then, he will sustain her in his Holy Supper, and with his life-giving Word.
