The believer is no longer in Adam, but in Christ. You are out of Adam and have disinherited all he sold you out to! You are in Christ and have inherited all He purchased for you! Adam sold you out to the slavery of dominion of Satan, but Christ paid for and totally purchased your freedom and victory over your past. 
As long as you see yourself in Adam, you will be part of his dysfunctional family, but the moment you see yourself in Christ, you become a part of His functional family who has victory over the disorders that are in the world. I like to say it this way: Jesus put the "fun" in functional living.
