Job 37:19: Surrounded, sunk in deepest night

Surrounded, sunk in deepest night,
To God how can I speak aright,
In order all my wants declare,
Or offer an accepted prayer?
Alas, I know not what to say,
I know not how to plead or pray,
Unless He hears His Spirit's groan.
And God replies, It is My Son!

With darkness palpable oppress'd,
Father, I would Thy grace request;
But what, and when, and how I leave,
And wait Thy time and way to give:
I neither speech nor utterance find.
But, Lord, Thou know'st Thy Spirit's mind.
Thou know'st my Surety on the tree,
And all He purchased there for me.
