Why won't God heal amputees

This question is something that athiests normally bring up claiming its a proof that God is not all powerful because he should help amputees.

The answer is simple when a part of a person has to be removed then they have a choice. Either allow the medicial problem to kill the person or sacrfice the limb to save the person.

So this is the help. Rather than die they cut off a limb. So the help was always there. Its just another illogical argument presented by atheists.

God has already helped them because they lost a limb instead of death.
