"We can stand affliction better than we can prosperity, for in prosperity we forget God."--Dwight L. Moody

For the most part, Dwight probably has a point.
We tend to see the almighty as a parent who will bail us out when we run into trouble so we whine and beg (read: "pray") to our deity of choice when times get tough.
When times are easy, who needs a spiritual or parental handout?
But let's look at this from God's P.O.V.  Don't you think that, like a parent, he or she would get a little tired of the childish tantrums and tears we display when we don't get what we want or we're hurt in some way? Don't you think God would welcome our forgetfulness when things go well for us?
I think he/she would say what a harried parent would say when their two-year-old has finally gone to bed:
"At last, some peace and quiet!"
