The Greatest Gifts

As a child, anytime that I was behaving poorly, my mom would tell me that Santa Claus was watching. That would straighten me right up. After all, who wanted to miss out on Santa's great gifts at Christmas time? So my question is, as adults, why do we not behave as though Jesus is always watching? Especially when we're behaving poorly? He is watching, you know? And if we did live that way, wouldn't we all just straighten right up? After all, who wants to miss out on God's greatest gift..... Heaven?
