I was so surprised when you quoted this verse from the Bible. You know why ? The day my son was born, me and my wife cried a lot and opend the bible blindly and we read exactly this verse. It was a great comfort. Still after 6 years when people harshly comment that, it is our sin why God gave us a child with this kind of problem, I always tell them to read this verse.
I think God has every reason to use it for his Glory.
God bless you.
