Just Words?

Then Joseph brought in his father, Jacob, and presented him to Pharaoh.  And Jacob blessed Pharaoh. [Genesis 47.7]

Then Jacob blessed Pharaoh again before leaving his court. [Genesis 47.10]

Then Peter said to Jesus, “Explain to us the parable that says people aren’t defiled by what they eat.”  “Don’t you understand yet?” Jesus asked.  “Anything you eat passes through the stomach and then goes into the sewer.  But the words you speak come from the heart—that’s what defiles you.  For from the heart come evil thoughts, murder, adultery, all sexual immorality, theft, lying, and slander.  These are what defile you.  Eating with unwashed hands will never defile you.” [Matthew 15.15-20]

May the words of my mouth and the meditation of my heart be pleasing to you, O Lord, my rock and my redeemer. [Psalm 19.14]
 
Is there a theme here?  How can we deny it?  Words have the potential for great power.  The words we speak are much more important than just casual conversation!  Unfortunately, for the most part, mankind has ceased to believe this any more.  Words are now something thrown around randomly based on emotion or circumstance with no regard for their power.  Our first historical account of spoken words quite literally erupted with creative power as God "spoke" and the world was created.  It seems that faith has been removed from words nowadays.  God's original words were spoken with expectation.  Jacob's words of blessing were spoken with expectation.  Even the woman who pursued Jesus today (and quite frankly verbally prevailed with Him) spoke with expectation!
 
Ah, but today, we label a person a freak if they claim such power in their words.  We shy away from speaking things that are not as though they were.  Words have become the language of what WAS rather than the driving force of WHAT WILL BE.
 
Father, my prayer today has already been prayed: May the words of my mouth and the meditation of my heart be pleasing to you, O Lord, my rock and my redeemer.
