From the recording Roughing It
Written during Lent. It strikes me deeply that the lepers that approached Jesus pleaded for mercy, yet rather than expectantly say "heal us," they humbly acknowledged both Jesus's power and volition to heal.
Lyrics
Son of David, Son of David
Have mercy, have mercy on me
If you choose, you can make me clean
I am forgotten like one long dead
He has made my flesh waste away
I am bent low, my home among the ashes
A flood of tears by night and terrors in the day
Son of David, Son of David
Have mercy, have mercy on me
If you choose, you can make me clean
My food is bitterness and my cups is full of gall
Gone is my glory and my soul's bereft of peace
But I will hope in God as this I do recall
His steadfast love and mercy will never cease
The Lord is good to those who wait for him
His anger's a moment, His favor's eternity
I'll cry out, not resting, my eyes will flow
Until the Lord looks down from heaven
And gives relief
Son of David, Son of David
Have mercy, have mercy on me
Have mercy, have mercy on me
If you choose,
If you choose, you can make me clean
