Luke 12:48

But the one who did not know [i.e., what his master wanted], yet did things deserving of punishment, will be whipped with few lashes. And to the person who has been given much [responsibility], there will be much required [of him]. And to whom people entrust much [responsibility], they will ask [much] more from him.

Romans 14:23

But the person who has doubts about eating [a certain food] is self-condemned if he [goes ahead and] eats it, because his action is not based on faith [i.e., if he lacks the conviction that he is doing what is right]. And whatever is not done with such a conviction is a sin.
