God Is a Host Yet One - Question on the Trinity

QUESTION RECEIVED:

On Isaiah 6:8, who does God mean by "us" when he said "who will go for us?" The seraphim?(Isa 6:2) The Trinity? Or a group of prophets?

MY ANSWER:

In the verse you referenced, Isaiah 6:8, God is talking to a group. Te group was Himself!

Isaiah 6:8 English Standard Version (ESV)
Isaiah’s Commission from the LORD

"8And 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."

In Isaiah, The King had a message to send. The message was not sent from mere servant angels or mere men. The King of Glory sent it forth.
God is a group of completeness in Himself. The Trinity is a mystical fact that we can never fully understand yet we will be more awed by it the more we learn about Him.

Despite some of our weak theological thinking, God did not create humanity because He was lonely. Our great God is in His fullness in the Godhead of God The Father, God The Son and God The Holy Spirit is more vast than infinity. The fullness of each members personality and uniqueness is staggering. They are all fully separate in personality yet fully complimentary to each other though they are all yet fully God.

In Genesis, at the time of creation, verse 1:26 tells us about the fullness of the Godhead or what we call the Trinity.

Genesis 1:26
English Standard Version (ESV)
"26Then God said, "Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth."

The "Us" in Isaiah 6:8 is the "Alpha and Omega" the "First and Last".
Study and worship this great God.
