The Reaction of My Life...

I thought this was a different perspective...
"Once you have the right relationship with God... remember that whatever your circumstances may be, you have been placed in them by God. And God uses the reaction of your life to your circumstances to fulfill His purpose," (more here).
Interesting that God wants to use "the reaction of my life". How often do I find myself in a crappy situation and I react like a bratty kid? Or at least on the inside cuss and fuss... Looks like I need some more fruit growing on this tree.
