I'm just re-reading some good books on prayer. The most important thing about prayer, is getting to know God better.
When we know him better, it doesn't seem wrong to bring those important requests, and the small things before him.
As for me, the knee has improved 100% since yesterday, thanks to all who prayed. On a bad note, I now have my entire left foot flared - swollen like a balloon. We had to go change our driver's licenses and health care to BC today, and I had to ride in my wheelchair. I was worried people would treat me like an idiot, but they were all very nice! I'm so glad everything was equipped for wheelchairs.
