What is Joy?

Today in Sunday school we discussed this topic. What is joy? Of course, everyone has a different definition, but all mean the same thing. Joy can be something as simple as a smile to someone who rarely receives a smile from a stranger or joy can be simply a hug.
Think about it. What is joy...to you?
Try to share the joy you have with others, not only in this season of giving, but in every season; because after all, Jesus didn't just give to us one time a year.
