God with a Physical Body Created Man in Their Image

Gospel Through the Ages, pg 104; “Mormon prophets have continuously taught the sublime truth that God the Eternal Father was once a mortal man who passed through a school of earth life similar to that through which we are now passing. He became God—an exalted being…” – Milton Hunter

Genesis 1:26; “And 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 fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.”

If God is an exalted man then why did he say “let’s make man in our image”? 

Why ddn’t he say I’m going to make man in my image?  

God’s word tells us that He is spirit in John 4:24. It tells us that Jesus would be called Emmanuel, Matthew 1:23 and why does Paul tell us the Spirit of God dwells inside us – 1 Corinthians 3:16?  

All of these verses paint a picture of the Triune God!  God in three persons, blessed Trinity as the song goes.  How could He be an exalted man and the Holy Ghost not be part of God if these scriptures are true?
