Singing in Sorrow

A friend mentioned that she's been taking great comfort in Psalm 13, so I've been reading over it today, too.

To the choirmaster. A Psalm of David. 

How long, O LORD?
Will you forget me forever?
How long will you hide your face from me?
How long must I take counsel in my soul and have sorrow in my heart all the day?
How long shall my enemy be exalted over me?
Consider and answer me, O LORD my God;
Light up my eyes, lest I sleep the sleep of death,
Lest my enemy say, "I have prevailed over him,"
Lest my foes rejoice because I am shaken.
But I have trusted in your steadfast love;
My heart shall rejoice in your salvation.
I will sing to the LORD, because he has dealt bountifully with me.

He truly has dealt bountifully with me.  Even when I "have sorrow in my heart all the day" that doesn't change his steadfast love.  It's still worth trusting.  Light up my eyes, Lord.  Help me to sing.
