As for how long sanctification - becoming a new creation - takes, well in my case decades but I'm probably a challenged sluggish learner, struggling to apply Jesus' teachings and His apostles' teachings (The Father's teachings) in my life. I reckon however long it takes to come to enough knowledge of the truth and enough faith in the message of truth from God to be set free from lying and hating and other such things, it comes to an initial fulifilment when the Holy Spirit is clearly heard within - the wind from whence you do not know where it comes or to where it goes. Then rebirth has become a reality for you but sin after that is dealt with by the Father - now your father - giving you life and others praying Him to do so. That can mean painful discipline. But a new creature has come into the world.
