I really believe that this current body is not our initial state, Genesis 1:26 where God says that he made us in his image and likeness, and God Jehovah is spirit, not body.
That means that our state of body made and composed of flesh, is the result of the spirit of God mixing with sin, when Adam disobeys God and consumes the tree of knowledge.
Romans 6:23 explains that the wages of sin is death, by dying to the flesh, we only have to be a spirit and that is why it is necessary to die since that will return us to our initial state. Be a spirit with God our Lord.
unfortunately I did not understand the video very well since my language is Spanish. But I really like to talk about the bible and jehova.
