Mourning into Dancing

This text of Psalm 30 caught my attention recently:

As for me, I said in my prosperity,
    “I shall never be moved.”

By your favor, O Lord,
    you had established me as a strong mountain;
you hid your face;
    I was dismayed. To you, O Lord, I cried,
    and to the Lord I made supplication:

“What profit is there in my death,
    if I go down to the Pit?
Will the dust praise you?
    Will it tell of your faithfulness?
 Hear, O Lord, and be gracious to me!
    O Lord, be my helper!”
You have turned my mourning into dancing;
    you have taken off my sackcloth
    and clothed me with joy,
 so that my soul may praise you and not be silent.
    O Lord my God, I will give thanks to you forever.
Psalm 30:6-12
