God helps those who help themselves and does not help those who do not help themselves. Antibiotics are more powerful than God as they help:
a) those who help themselves, i.e. those people X who take antibiotics when in need, and
b) those who do not help themselves, i.e. those people Y who do not need to take antibiotics, i.e. those Y that have not been infected by X because X had been cured by the antibiotics before they met Y.
