Charles Spurgeon Commentary Isaiah 6:8

"And I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then I said, Here am I; send me." — Isaiah 6:8 (ASV)

Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I, send me.

Observe the unity and the plurality: Whom shall I send, and who will go for us? Upon what theory, other than the doctrine of the Trinity, can we explain so singular a change from the singular to the plural in the words, Whom shall I send, and who will go for us? Then said I, Here am I. send me.?

This man, so lowly now, so purified by the vision of God he had just seen, how cheerfully does he spring forward at the word of invitation! Here am I, send me.

Now see what a sorrowful mission God, in these next verses, assured Isaiah that his ministry, as far as the conversion of the Jews was concerned, would be altogether fruitless; they would not receive his testimony.

Also I heard the voice of the LORD, saying, Whom shall I send, and who will go for us?

Here we have the Divine Trinity in Unity. "Whom shall I send?"

There is Unity. "Who will go for us?" There is the Trinity. God is seeking a messenger to deliver his message to men.

Then said I, –
Stammering it out with the blistered lip, –

Here am I; send me.

Isaiah did not know the errand; perhaps, if he had known it, he would not have been quite so ready to go; who can tell? But God's servants are ready for anything, ready for everything, when once the living coal has touched their lip. I thank God that I was never called to such a work as Isaiah had to undertake.
