I posted this as a comment to David Dickens' poem "O Eye!" You may want to read his poem first, although this one will also stand alone.
So many people, with Christ’s name,
So resistant to a praying word
Maybe fearing finding truth
Maybe feeling “I’m not good”
Maybe never having known the joy
When two or three become much more
As God himself arrives among them
For where two or three are gathered in my name,
there am I among them.
--Jesus, in Matthew 18:20
