There is only one God. He alone created the universe.

                                                                

"In the beginning God created the heaven and the earth." - Genesis 1:1

"For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else." - Isaiah 45:18

In the book of Colossians, it speaks of the Son creating all things. How can this be if there is only one Creator, and that is the Lord God?

Colossians explains that the Son is the image of the invisible God. The invisible Spirit of God put on the flesh of humanity and became visible. This human is called the Son of God. All the fullness of the godhead is within this man.

"For in him dwelleth all the fulness of the Godhead bodily." - Colossians 2:9 KJV

It is the One True God that dwells in the body of the Son that created all things. Thus, in the beginning, God created the heaven and the earth. The same God that dwells in the Son is the One True God that created all things.

"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. And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. For it pleased the Father that in him should all fulness dwell;" - Colossians 1:16-19 KJV

The Father – who is Spirit – dwelt in the Son – which is flesh. God revealed His name of salvation is Jesus.

The reason the Father, Creator of the universe, put on flesh was so that He could pay the price of sin for mankind. This took the shedding of sinless blood, which only God could provide.

"Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: in whom we have redemption through his blood, even the forgiveness of sins: who is the image of the invisible God, the firstborn of every creature:" - Colossians 1:13-15 KJV
