The Face: A Reflection of the Heart

Proverbs 15:13 says, "A glad heart makes a cheerful face."  I think the Proverbial writer here is expressing an extremely common sense point.  Even children get this.  Our actions will reflect the state of our heart.  When our heart is happy, we naturally smile.  When we are depressed to the very core, our outward appearance reflects that.  We all acknowledge this truth in everyday life but for some reason we don't apply it to our worship.

-Why on Sunday morning when we're singing praise to our Father for all the glorious things he's done, do we have stone faces?
-Why do we get excited over a new ipod but our forgiveness doesn't even merit a sincere "Amen!"?
-Why do we show excitement at a concert but when a soul is saved at baptism we give nothing but blank stares?
-Why is it that we think God wants to see a coat and tie but not heart-felt hands reaching for the Father?

Are our emotions concealed in our worship in the name of "order?"  Should they be?  Maybe... to a certain extent.  But should they really be cut off all together as happens so very often today?...  Or how about I ask the real question.  Are we really all that in love with Jesus to begin with?  Think about it.
