This might have been how I should have ended last Sunday’s sermon (David’s Sin).  I ran across it today in Celtic Daily Prayer (it’s Ignatius of Loyola day in their calendar, and this was linked to the brief biography there):

O God,
I cannot undo the past,
or make it never have happened!
— neither can You.  There are some things
that are not possible even for You
— but not many!

I ask You,
humbly,
and from the bottom of my heart:
Please, God,
would You write straight
wit my crooked lines?
Out of the serious mistakes of my life
will You make something beautiful for You?

Teach me to live at peace with You,
to make peace with others
and even with myself.

Give me fresh vision.  Let me
experience Your love so deeply
that I am free to
face the future with a steady eye,
forgiven,
and strong in hope.
