Willful vs. Unwillful Sin
God differentiates between two types of sin: On purpose and not on purpose.
“On purpose” sins are willful and presumptuous. “Not on purpose” sins are non-willful and ignorant.
In this case, the person knows that the action he’s considering is sinful. After deliberating whether or not to proceed, he willfully and presumptuously decides to proceed.
Here, the person proceeds with an action and is not aware that it is sinful. He does it in ignorance of the fact that it is sinful, and doesn’t presumptuously sin. It could be an instantaneous reaction to a situation that suddenly occurred and the Christian reacted without thinking. Such as uttering a bad word (filthy communication out of the mouth). Such as telling an untruth and not knowing it’s untrue. It could be such as working with others on a job and an accident occurs and someone else is hurt or killed. And so on. It’s an un-willful sin: a mistake.
Scriptures pertaining to willful sin:
Scriptures pertaining to non-willful sin:
From the above scriptures we can see that the non-willful (ignorant) sins are forgiven, and that the willful (presumptuous) sins are not forgiven. In Numbers 15:30-31, the person is “shall utterly be cut off; his iniquity shall be upon him.”
In Hebrews 10:26-27, the person loses his soul forever as “there remaineth no more sacrifice for sins”.
