God works through people...

Ever been in a situation where you know things are happening, or you know that you are doing things but you also know that what is happening is not controlled by you?
I've heard stories of people saying: it was like something or some-one else was pulling the strings. I've always took such tales with a pinch of salt, because as we all know, human nature is to exagerate the facts somewhat. I've never discounted such tales as outright lies, but I always employed a healthy dose of sceptisism whenever I heard them.
After yesterday, this fact about me has changed forever.
Let me just say, first of all, I believe that if you are endowed with the Holy Spirit, great things are accomplished THROUGH you by GOD. Likewise if you are possesed by an evil spirit, horrible things happens.
What I am refering to here is not demon possesion, but God possession.
I was visisting my friend yesterday (her name is Carla), when we heard screaming coming from outside. Our first thought was that one of the kids got hurt. When we got outside and followed the screaming, we saw Carla's neighbour kneeling next to her husband in their front garden. He had just collapsed, having what we suspected a heart-attack. As I was running towards them I felt such an immense pressure to pray that it took my breath away. I kneeled down but the only words that I could come up with was PLEASE LORD SAVE THIS MAN.
Many many years ago, I took a first aid course that I did fairly well in, but since then, I have never practised my qualification. As I was kneeling there I thought to myself: I CANT REMEMBER WHAT I MUST DO!!! This man was dying, the ambulance was taking it's own time, AND I JUST CANT REMEMBER!
At that point it was asif my mind just went blank. Carla's husband later told me I saved that man's life. My son called me a hero. Apparently I started CPR on that man.
Let me tell you that I know, for as sure as I'm typing here, my actions yesterday, WAS NOT MINE. The breath that I blew into him was not mine; the hands that massaged his heart was not mine. By the time he started breathing again by himself I was spent. I felt lame. And I felt like I was in shock.
My son was very surprised when I told him later that I knew he thinks I was hero, but that he must know that it was not me working there yesterday. He didn't quite understand what I meant. My mind still stands still if I think that that man would probably not have made it, if God did not step in right there and then. And I can just humbly bow down and praise God for doing His work through this very imperfect human being. That He found me worthy to work through in spite of my faults, my sins...I feel like He must have made a mistake somehow; that He chose the wrong person for His works. Of course I know that God doesn't make mistakes. I just find it amazing that He felt confident enough to use me. I certainly did nothing to deserve such an honour and blessing. And I certainly don't have the same confidence in me than what He has!
