Next time you are boarding a flight kindly ask for a pilot who doesn't neccesarily have flying skills but says he is graced to do it, then we will understand.
If we don't make this clarification, people will place a distintinction between their "church life" and their everyday engagement. They will not be able to make a meaningful connection with the spiritual.
Grace doesn't come upon skill, grace produces exceptional skill unattainable by human ability.
