His strength.

David writes:
"I waited patiently for the Lord;
he inclined to me and heard my cry.

He drew me up from the pit of destruction,
out of the miry bog,
and set my feet upon a rock,
making my steps secure.

He put a new song in my mouth,
a song of praise to our God.
Many will see and fear,
and put their trust in the Lord."
-Psalm 40:1-3

These words have been so much of an encouragement this last week.
Sometimes I think I'm not strong enough for a job like this one.  Then I have to be reminded that my strength will always be insufficient on my own.  It is God who pulls us up onto a rock.  It is God who hears those cries of desperation.  HE is the one who makes all things work.

Let us praise God for his goodness. :)
