Answered Prayer

What is it called when God answers a prayer you haven't even prayed? I've had that happen to me twice recently and I'm convicted that I need to be praying about everything, no just for other's salvation or healing, etc. For example, I sold my treadmill a month or so ago and had planned on looking for an exercise bike. Well before the people who bought the treadmill even had come to pick it up, I got a call from a friend who told me that her mother wanted to give me her exercise bike--no charge! And so today, I was feeling bummed and stressed about figuring out how to see my doctor and wrote the post following this one. Not an hour later, I see a friend who says, can my husband and I watch your kids for you so you can see the doctor? I'm getting tears in my eyes as I type this. Amazing how God provides what we need before we even get a chance to ask! Praise God!
