Jesus has always existed. He existed before the creation of the universe with his Father and the Holy Spirit (John 8:58).
In fact, the universe was spoken into existence by Jesus (John 1:3). Everything in all creation was created by Jesus and for Jesus.
Currently, everything in the universe is being held together by Jesus (Col. 1:15-18).
He is Lord over all.
No person, creature or being can take his ranking or title as Lord. He stands apart and alone from all others. His very nature and work declares that He is Lord over all.
