When Has God NOT Answered Your Prayer?

The readers of this blog have been extremely helpful as I’ve worked through issues around prayer, in preparation for my next book, Why Pray? Thanks to those of you who answered Do You Pray? and for those who told me about a time when God Answered Your Prayer. (Those are still open, if you’d care to contribute.)

Now, I’m interested in hearing When God Did Not Answer Your Prayer? And also, what you did with God’s non-response? That is, how did you reconcile your understanding of God with God’s silence in the face of your request?
