If Jesus is part of Jehovah's being/existence/entity then many of the scriptures that have Jesus identifying himself as God make sense. Including when Jesus is about to be arrested and he identifies himself as "I AM" and everyone falls to the ground. Also, when he says he made God's name known which he was given.
This is one of the reasons Paul identified Jesus and God being a mystery. Paul could barely grasp that Jesus came from Jehovah literally. He is part of Jehovah such as his "right arm" like the scriptures identify him. This is the reason why so many scriptures interchangeably use God and Jesus both acting in the same capacity with the same authority. This is something that I could never reconcile while I was a JW. How the scriptures both spoke of Jesus and God acting in unison.
