Disbelieving faith?

This is going to be short....I still don't know how to title it yet. Hopefully a title will come to mind by the time I'm done writing.
So I was just listening (yes, listening) to the book of Acts as I worked (multitasking is my thing ;P ) Acts 12 caught my attention. That's the chapter where King Herod Agrippa began to persecute believers in Christ....So our very own Peter was caught and thrown in prison...
Acts 12:5 says "But while Peter was in prison, the church prayed very earnestly for him."
I am certain they were praying for his release...
Now, let's jump to verse 15...
What was the reaction of the people who were earnestly praying for Peter's release when Rhoda opened the door, saw Peter, closed it in his face and excitedly ran back to tell the church that their prayer had been answered?

"You're out of your mind!"

They concluded she was crazy.
Now, Rhoda knew what she'd seen and she wasn't going to be convinced that she was crazy (some people can make you doubt what you know to be true and I believe the church could have easily had some of us...)
Anyways, so Rhoda wasn't going to have her mind toyed with so she insisted. And what was the church's reaction to her insistence?
Rhoda was no longer out of her mind. They now believed...but,
"It must be his [Peter's] angel"
Now, I don't know if that meant they assumed Peter dead and had taken the form of an angel...All I know is, they were certain it was not Peter in the human form standing at the door....and this is what got me.
How many times have I not been like the church which was earnestly praying for Peter?
How many times have I not earnestly prayed to God on a subject, have Him answer me and then express profound surprise at the result I'd been praying for? It's not as if I do not have the faith required to see my prayer answered.
It is more like surprise at having God answer a faith based prayer. Sometimes, it's got to do with the speed with which God answers. Other times, it's as if I was just praying out of duty and was not expecting God to answer (which is is not the case) in the way in which He did answer.
Anyways, got to go back to work.
Just some running commentary on what was going through my ears :) ... and a good way to update my blog :)
