Anyone, then, who knows the right thing to do, yet fails to do it, is guilty of sin.

Luke 12:47
That servant who knows his master's will but does not get ready or follow his instructions will be beaten with many blows.

John 9:41
"If you were blind," Jesus replied, "you would not be guilty of sin. But since you claim you can see, your guilt remains."

2 Peter 2:21
It would have been better for them not to have known the way of righteousness than to have known it and then to turn away from the holy commandment passed on to them.

Therefore to him that knows to do good, and does it not, to him it is sin.
