"Do not use harmful words, but only helpful words,
the kind that build up and provide what is needed,
so that what you say will do good to those who hear you.
And do not make God's Holy Spirit sad; ...
Get rid of all bitterness, passion, and anger.
No more shouting or insults,
no more hateful feelings of any sort.
Instead, be kind and tender-hearted to one another,
and forgive one another, as God has forgiven you through Christ."

(Ephesians 4.29-32 GNB)

The world can be a much nicer place if everyone heeds these verses. It can start with all who profess to be Christians.

Lord,
"may the words of my mouth and the meditation of my heart" be filled with "only helpful words".
