They both had a common title. Luke, in the narration of the human genealogy of Christ, calls Adam as “son of God”. He wrote:
Adam, which was the son of God. (Luke 3:38)
Jesus, as we all know, in the famous text of John 3:16, is also called the Son of God. Adam and Jesus both had this common designation, though Adam was a created being, but Jesus is the Creator of all. The true Son of God is the “alpha and omega” (Revelation 1:8); He is God in the fullest sense. He has no beginning and no ending; He is the divine Son of God.
Jesus is the ruler of the entire creation of God. He is called:
KING OF KINGS, AND LORD OF LORDS. (Revelation 19:16)
Talking about Christ, in his epistle to the Colossians, Paul writes:
Who is the image of the invisible God, the firstborn of every creature: For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist. (Colossians 1:15-17)
Christ is called “the image of the invisible God”. Elsewhere Paul wrote:
Who being the brightness of his glory, and the express image of his person. (Hebrews 1:3)
Christ is the exact reflection of the Father. That is why He said:
He that hath seen me hath seen the Father. (John 14:9)
On the other hand Adam, the first man, was made in “the image of God” (Genesis 1:27).
As Christ has rule over all principalities and powers and dominion so also Adam was given dominion of this planet earth.
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. (Genesis 1:26)
The difference in the extent of their dominion was as high as heaven is to earth.
