What are believers predestinated to according to Ephesians 1?

Les explains that Ephesians 1:5 says believers were 'having predestinated us unto the adoption of children by Jesus Christ to Himself, according to the good pleasure of His will.' He defines adoption as Paul used it and as practiced in Roman and Greek culture: a child born of the husband and wife was put under tutors, educated, trained, and prepared to come in at an equal level with the father, then went through the rites of adoption. The Hebrew Bar Mitzvah at age 14 is akin but not the same category because Romans and Greeks were in the secular world, preparing the child to be a co-worker in the business. But Paul teaches that the moment we become a believer, we do not go through years of tutoring and training; we are immediately placed as an heir with the Father and the Son. Les says we were predestinated not to heaven, not to hell, but as a believer to this position with Christ from day one, as a joint heir in the process of adoption. Ephesians 1:11 also speaks of obtaining an inheritance, being joint heirs with Christ; if you are a joint heir, the other parties are yours, and in the secular economy, if the other half passes off the scene, the heir ends up with it.
