Thank you. My first read is it does not seem likely to refer to skills one can acquire (neither through formal western school e.g. medical school nor apprenticeship e.g. acupuncture or informal medical training). It does seem like either route would (could) pre dispose one to recognize or be open to the grace. But it reads like a grace bestowed selectively (from a human view point perhaps would look “randomly”) to select individuals for the good of the community. Just thinking about it past the first layer and it would take tremendous wisdom and prudence for someone to have such a grace and use it for the good it is - but not allow its use to lead one into pride or frustration or lend ones actions to be used to put God to the test. There are some graces I think I am glad I do not seem to possess.
