Praying thanks...

John Ortberg speaks of writing a thanksgiving letter to someone you're grateful for.  Write it, make an appointment to see them - and then read the letter to them.

You can imagine receiving such an appointment as a little bit awkward.  But it would be quite moving.

Writing the thanksgiving letter and reading it would also be quite an experience.

How about with God?

When we say grace before a meal, when we express our thanks in songs and prayers of praise at church - do we really feel the gratitude.
