Summary: We like to excuse many of our actions as “only mistakes” and “no big deal”. But God sees things differently as He speaks to us about our unintentional sins.
Everyone is familiar with the statement of Steve Urkle, “Did I do that?” after unintentionally creating havoc. We have all heard someone say, "I’m sorry, I didn’t mean it" or "Forgive me, I didn’t know I wasn’t supposed to..." We like to excuse many of our actions as “only mistakes” and “no big deal”. But God sees things differently as He speaks to us about our unintentional sins.
I. What is Unintentional Sin?
A. Unintentional Sin is a Sin of Ignorance
2. Modern day example: You get caught speeding in a 25 mile per hour zone, when you didn't realize that the speed limit had changed. Or going through a stop sign that you didn't see.
Just because you weren’t aware that you broke the law at the time you broke the law, you’re still guilty of breaking the law.
3. Paul is another example of having committed unintentional sin.
4. A man frequently does wrong for lack of thought, through not considering the outcome of his actions—or even thinking at all. He carelessly and hastily blunders into the course which first suggests itself and errs because he did not think about whether or not it was right.
5. Proverbs 7:22-23 (quickview)  “Immediately he went after her, as an ox goes to the slaughter, Or as a fool to the correction of the stocks, till an arrow struck his liver. As a bird hastens to the snare, He did not know it would cost his life
6. A sin of ignorance is committed quite often when there is no intent to do wrong and yet wrong is done. Many of the worst sins are committed with the best of intentions
B. Unintentional Sin is a Sin of Neglect
1. Numbers 15:22-24 (quickview)  (NLT) ““But suppose you unintentionally fail to carry out all these commands that the Lord has given you through Moses. And suppose your descendants in the future fail to do everything the Lord has commanded through Moses. If the mistake was made unintentionally, and the community was unaware of it, the whole community must present a young bull for a burnt offering as a pleasing aroma to the Lord. It must be offered along with its prescribed grain offering and liquid offering and with one male goat for a sin offering.”
C. A sin requiring a guilt offering was the unintentional breaking of special commands regarding religious duties. Examples given to Israel were neglecting to tithe, or eating the priest’s portion of a sacrifice.
