Exodus 4:10: How ready is the man to go

How ready is the man to go
Whom God hath never sent!
How timorous, diffident, and slow
His chosen instrument!
Lord, if from Thee this mark I have
Of a true messenger,
By whom Thou wilt Thy people save,
And let me always fear.
Slow of speech, and slower still
Of heart, alas! am I,
Cannot utter what I feel,
Or speak to the Most High:
But I to my Brother look,
Mighty both in word and deed:
He my cause hath undertook.
And lives for me to plead.
Jesus is my great High-priest,
Who doth in heaven appear;
Him presenting my request,
The Father loves to hear:
Jesus, (if His wrath arise.

And justice on the sinner frown,)
Jesus speaks and pacifies,
And prays His anger own.
Jesus is a mouth to me,
Expressing all my wants;

God is vanquish'd by His plea,
And every blessing grants:
O how eloquent His blood
Which echoing from the throne Divine.
Tells me, I am dear to God,
And all He is is mine.
