Celebrate - Lev 22:29-30

"And when you sacrifice a sacrifice of thanksgiving to the LORD, you shall sacrifice it so that you may be accepted.  It shall be eaten on the same day, you shall leave none of it until morning:  I am the LORD."  Lev. 22:29-30

A friend shared what came to mind when they really thought about this, and I loved what they said, so I'm sharing:

When sacrifices were made, it was whole animals; that means a LOT of food/meat.  This had to be eaten the same day.  To consume this amount, it could very well have been possible that families invited others over to celebrate with them, and this was a sacrifice of thanksgiving. 
In our society, we gather together to celebrate birthdays, holidays, etc.  Why don't we start holding celebrations (cookouts) of thanksgiving to our LORD for things that He's done in our lives; giving Him thanks and blessing Him?  Sounds like an excellent idea to me.
