Jesus said" I am come that ye may have life and have it more abundantly" That life is the nature of the Father .A person is recreated by receiving God's nature into his spirit,which makes him/her a new creation and gives him/her a new self. The old self was selfish.but this new self is Love-ruled.This new life is like jesus. It is the substance and nature of Jesus. It is loves dominion over man.The Holy Spirit comes into the persons body and brings in more love. Romans 5:5"For the love of God is shed abroad in our hearts by the Holy Spirit."
