Larry,
I sent a rather long PM to you.
This is absolutely childs play for the Lord. Rastaman has it right, do not speak death, you do not have anything, do not claim it, you are being attacked, speak only positive words (hard I know, but remember, we hold life and death in our words, don't make yourself a profit in a bad way). And don't pray wimpy prayers such as, oh Father if it is your will please heal me....Screw that, He is your Father, would you wish anything bad happen to your son? No, neither does He.
Something like, Father God I boldy ask for healing for it is written "by your stripes we are healed" Lord you said if you ask you shall receive..and the one where most people fail, be it done to you according to your faith. If you do not believe, or have faith, you will not be healed by the Lord.
