Luke 12:48

while one who does not know his master's wishes, but acts so as to deserve a flogging, will receive but few. From every one to whom much has been given much will be expected, and from the man to whom much has been entrusted the more will be demanded.

Romans 14:23

He, however, who has misgivings stands condemned if he still eats, because his doing so is not the result of faith. And anything not done as the result of faith is a sin.
