Intercessory Prayer Disciple Training

I'm taking Intercessory Prayer Disciple Training(IPDT*) from church.
It's 3rd week, and we prayed for our church and for the each parts of the church.
And in the day of 2nd and 3rd week of IPDT, I was having stomach trouble. 2nd week I threw up twice, and I prayed that God to heal me continuously for 30 min. and He did. Today(actually yesterday 02-25-10) I had headache. I think it's from lack of sleep, but that headache got me a stomach trouble. I don't know why, but when I have a headache I can't digest very well. I see this as attack of devil, trying to fall down from the training, but I declare in the name of Jesus: "In the name of Jesus, be gone the devil who makes me sick in order to get me fall away from the training. Be gone!" I believe Jesus will deliver me. Also, I didn't do my QT even though I had enough time for it. I went to Office hour and tried to configure so that I could use one of GUI in Linux, and I wasted so much on that, so I couldn't do my QT. I already meditated about this, and I failed again by putting the world in front of Jesus. I confess that this is sin to Jesus. Lord, I will not change by myself and will continuously go back to the same sin: loving the world. Please Lord, hold on to me and change me by the blood of Jesus Christ. God, oh God save my soul. Without the Cross, I would be dead in front of You, but I thank you that blood of the Lamb saved my soul. This world won't be anything at the end of the day, and will be just a dust. I hold on to You Lord, since You made me to hold on to You. I praise Your mercy and grace. Let the blood of Jesus Christ go thru me and fill my cup, so that it overflows to other people to have this peace and love that no world can give.

*IPDT is not really what it called, it's just for sake of easiness of writing it.
