Christ, the Creator
Col 1:15-17 He is the image of the invisible God, the firstborn over all creation. For by Him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by Him and for Him. He is before all things, and in Him all things hold together.
"The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word." Heb 1:3a
Jesus is the Creator. For "through him all things were made; without him nothing was made that has been made." John 1:3, which also indicates that Jesus was not a created being. What it means here in Col of Jesus being "firstborn over all creation" is to say that he takes precedence over creation. There's creation, and then there's Jesus. Jesus takes precedence over creation. "You are worthy, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they were created and have their being." Rev 4:11
Not only were all things created by Jesus, but all things were also created for Him. You were created for Jesus. "And He died for all, that those who live should no longer live for themselves but for Him who died for them and was raised again." 2Cor 5:15
