I wonder what an idle-word is.  Are they the words we say off the top of our head?  Are they the mean, uncaring words we speak in anger?  Are they lies we speak, or are they insincere words of flattery?  Perhaps they are all the above.  I know I need to repent often.

There are all Kinds of Words

Words are everywhere; word kind and sincere,
Or words that are unfair and unpleasant to the ear.
Words can lift up, or words can tear down.
Some words can be counted on, they are true and sound.
Some words are misleading, and others a shame.
Some glorify God and others defile His good name.
Words give praise and thanks and also curse sounds too.
There are words of doubt and fear and some in faith, mountains will move.
There are whining words that murmur, and harsh, angry words that destroy.
There are words that cause heaviness and some spread certain joy.
Words like sweet waters, or utterances salty that sting.
Some promote evil, and others pleasure the King.
What are your words? Are they easy to recognize as good and true?
Or is your expressions seen as a dishonor to both God and you?

Matthew 12:36-37
But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment.  For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
