I have been pondering this selection ever since I read it in Abandonment to Divine Providence last night. 

Souls who walk in light sing the hymns of light; those who walk in the shadows chant the hymns of darkness.  Each must be allowed to sing through to the end the words and melody which God has given him.  Nothing must be changed in what he has composed.  Every drop of distress, bitter as gall though it may be, must be allowed to flow, no matter what its effect on us.  It was the same for Jeremiah and Ezekiel.  They found consolation only in continuing their laments.  Had their tears been halted, we should have lost the loveliest passages in Scripture.

I have felt for many years that God has had me walking in the shadows rather than walking in the light.  This is a very thought-provoking passage for me.  He is not talking about a hopeless type of lament, but true lament, sung in God and to God.  Michael Card, in his book Sacred Sorrow, talks about this very thing, the importance of lament.  (I have more to say about this, but not the time today.  More later.  But I’m interested in your thoughts.)
