In the beginning Adam carried all of humanity in him as a seed but when they sinned the entire generation of humans were cut off.
The scripture we read explained what Jesus did as the last Adam carrying the seed of the new race or new creation.
We are not a refurbished spirit we are a new creation a completely new being having existed only in Christ as long as you are born again. The moment you accept Jesus one of the seed in Jesus come into you.
It is the knowledge of the truth that brings understanding to you.
What the holy spirit does is to unveil Gods word to us as long as you are in close fellowship with the holy spirit by reason of the consciousness.
