What next, a Christian EMT who refuses to treat an accident victim who was driving a beer truck, since if they let them die, they will no longer be delivering the "devil's brew". Puhleeze!!!!
I completely relate to your convictions. As a bartender, you are helping him/her as an individual person, not a corporation with it's employee on the books. The longer the employee waits, the more money they make anyhow right?
I do not feel the Holy Spirit is necessarily consistent in offering personal convictions so we shouldn't be. Follow the holy spirits guidance.
Your brother may admire you for it, and/or reolize he is loosing a valuable employee as someone mentioned.
Hopefully both will occur.
