response to good-limb amputations

yea...as i said i dont know what to think of it. its just sooo unheard of...sooooo out of the norm of the majorital society (i might be making up words...) but me and my Christian values are always getting in the way of looking at situations objectively. i say God gave you that body with the right amount of limbs or not for a reason. if you were born with all your limbs it could be because youre meant to do something only a whole properly functioning body can do & talk to someone about something that can save their life and the lives of all their relatives. you say im a nutcase but anything can happen/ anything is possible. the point is if you get something amputated that rules you out for that amazing purpose of saving lives and God might find someone else to do it...or he might allow those people to be lost because you were the only one He chose for that purpose...it seems hard to understand for people who dont believe in Him. i guess in that way its a sin because were accusing God of making a mistake when he made us. i know its psycological but there has to be a root where all this type of thinking begins......im frustrated
