Psalm 139

This psalm of David makes me feel much better every time I read it:

O Lord, you have examined my heart
  and know everything about me.
You know when I sit down or stand up.
  You know my thoughts even when I'm far away.
You see me when I travel
  and when I rest at home.
  You know everything I do.
You know what I am going to say
  even before I say it, Lord.
You go before me and follow me.
  You place your hand of blessing on my head.
Such knowledge is too wonderful for me,
  too great for me to understand!

I can never escape from your Spirit!
  I can never get away from your presence!
If I go up to heaven, you are there;
  if I go to the grave, you are there.
If I ride the wings of the morning,
  if I dwell by the farthest oceans,
even there your hand will guide me,
  and your strength will support me.
I could ask the darkness to hide me
  and the light around me to become night-
  but even in darkness I cannot hide from you.
To you the night shines as bright as the day.
  Darkness and light are the same to you.

You made all the delicate, inner parts of my body
  and knit me together in my mother's womb.
Thank you for making me so wonderfully complex!
  Your workmanship is marvelous - how well
    I know it.
You watched me as I was being formed in utter
  as I was woven together in the dark of the womb.
You saw me before I was born.
  Every day of my life was recorded in your book.
Every moment was laid out
  before a single day had passed.

How precious are your thoughts about me, O God.
  The cannot be numbered!
I can't even count them;
  the out number the grains of sand!
And when I wake up
  you are still with me!

O God, if only you would destroy the wicked!
  Got out of my life, you murderers!
They blaspheme you;
  your enemies misuse your name.
O Lord, shouldn't I hate those who hate you?
  Shouldn't I despise those who oppose you?
Yes, I hate them with total hatred,
  for your enemies are my enemies.         (Damn Satan and his demons!)

Search me, O God, and know my heart;
  test me and know my anxious thoughts.
Point out anything in me that offends you,
  and lead me along the path of everlasting life.
