Amputee Prayers

http://whywontgodhealamputees.com/

The question is simple, why doesn't God answer the prayers of amputees? The website leads to many well articulated criticisms of the power of prayer and the existence of God. But it pretty much boils down to this:

People believe that the power of prayer to heal wounds is real. The bible also makes claims in many different places [sited on the website] that a sincere prayer from someone that truly believes will lead to it being answered.

There must've been at least one sincere amputee who truly believes in God that has asked for a limb to be restored.

There has never been a case that a limb has been restored.

Either God has an odd divine plan for amputees that hasn't been revealed or god does not exist.
