"This law will always continue for you: On the tenth day of the seventh month, you must not eat food. You must not do any work. None of the travelers or foreigners living in your land can do any work either. Because on this day, the priest will do this to make you pure and wash away your sins. Then you will be clean to the LORD."
Leviticus 16:29-30 ERV
How seriously do you take sin?
Do yourself a favor and read all of this chapter in Leviticus. God takes sin very seriously. Throughout the year, the Israelites sacrificed animals for their sins and on the Day of Atonement, the sanctuary was purged. God gives specific instructions for this Day that the chief priest is to perform in order to cleanse the nation and the sanctuary.
We don't need to sacrifice animals. The sanctuary does not require purging any longer. Jesus Christ paid for our sins once and for all through His own blood. He was our scapegoat for all eternity. He was the perfect sacrifice for all of us.
Perhaps the Day of Atonement served another purpose also: reminding God's people of the seriousness of sin.
Take some time today and recognize God's view of sin and thank Him for the Perfect Sacrifice.
Then, remember, sin is serious stuff.
