The book of Colossians tells us the fullness of the Godhead dwells in Jesus bodily (Colossians 2:9 kjv), and we read in Romans 1:20 that the invisible things of God are clearly seen from the creation of the world…even His eternal power and Godhead.
People may be able to argue whether or not there is such a thing as the trinity, because the word trinity does not appear in scripture, but what about the Godhead?
Since scripture assures us the Godhead is revealed in the creation, the logical question would be to ask where in the creation is it revealed? That naturally takes us to the book of Genesis. In the very first chapter of Genesis (1:26), God said let “us” make man in “our” image.
Was God communing with the angels when he said this? He could not have been as there is no indication in scripture that angels are made in the image of God. God reserved that incredible privilege for mankind alone. Was the conversation recorded in Genesis 1:26 an example of what is known as “plurality of majesty” used by royalty when referring to themselves alone as “we” and “our”? God does not imitate man. The plurality of majesty came about from royal persons imitating the way God referenced Himself in Genesis 1:26, not the other way around.
Just as the apostle assures us in Romans chapter one, Genesis 1:26 clearly reveals a conversation between the members of the Godhead. Many scriptures shed more light on this. Jesus, the Son of God (also called the “Word” in John 1:1), is a member of the Godhead. We understand that from the clear language of Colossians 2:9. The Holy Spirit is a member of the Godhead. In Acts chapter five, the apostles clearly stated that lying to the Holy Spirit was the same as lying to God. And nowhere in scripture is there a clearer statement concerning the Godhead than in 1 John 5:7-8, where we read that there are three in Heaven, the Father, the Word, and the Holy Ghost, and that these three are one.
There is no doubt 1 John 5:7-8 (also called the Johanneum or Johannine Comma) is authentic. Detractors cannot account for early references (see the book, MY BIBLE DOESN’T SAY THAT! by Jocelyn Andersen).
The eternal Godhead was revealed in the creation of man. Man is made in God’s image, and that is a triune image—a composite unity. Man is a composite unity. Man is spirit, has a soul, and lives in a body. In man, there are three, and these three are one. Man, like the God in whose image he is created, is a three in one. Even if the existence of the soul is denied and only the spirit and body acknowledged, the fact that man is a composite unity is not changed.
The revelation of the Godhead in the creation of man is but one of the ways the invisible things of God is revealed in the creation of the world.
