I work in an optical shop, and one day an elderly gentleman brought in his wife's glasses.  The frames were broken and beyond repair.  The lenses were very strong and I knew the owner could not even function without her glasses.  The old style of frame was discontinued. And we had nothing like it in our store.  Then I remembered what I had in my car. 

While I was in optical school some 10 years earlier, my instructor had given me a discontinued frame to use myself.  All these years I had not done anything with them and had them in a box in my closet.  Just the week before,  I cleaned out that closet and had taken that frame and some old glasses out to give to the Lions Club.  Even though I had been by the drop box several times, I had not dropped them off.  Sure enough they were the ones in my car.  I was able to put her lenses into the frame and did this in about 20 minutes. 

The old man insisted I call his wife and tell her what had happened.  When I told her, she said she had been praying all that time, because she had a Bible class to teach in about an hour, to some college students and needed those glasses. 

I believe God knew she would need that frame 10 years before, and was providing.  After all the Word says He answers our prayers even before we ask.
