"Avi Ha'Oved" wrote in this amazing story (translated from an email we received in Hebrew):
For many years after the wedding, we didn't have children. We did tests and discovered that the chances for me to be able to ever have children were close to zero.
The doctor (who, by the way, is one of the top doctors in this field in Israel) didn't give me almost any chance. He even said it would be crazy to even try, but we insisted that he try to help us anyway.
To make a long story short, I always davened to Hashem who can solve all problems, and I requested from Him to help us because, "What do you mean? I must have a child!"
At a certain stage, after a few treatments that didn't work, we were ready to give up. I had been on GYE's 12-Step phone conferences for a while which had led me also to join the live SA groups. After being in the "program" for a while, I had learned what it means to surrender to Hashem's will. One day, I simply davened and said to Hashem in these words: "Your Will be done, not mine. If it is good for me to be without offspring and without leaving a remnant, so be it."
On that very day, we did another treatment and my wife became pregnant.
This is above nature, a real miracle!
