If you are a son of God, does that mean you are also an heir?

Les teaches that sonship and heirship go together for the believer. He illustrates it with a 12- or 13-year-old boy in a souvenir store who had become a full partner in his father’s business; the father let him act because he had never lost a dime. Les applies this: believers are no more a little kid under tutors, but are in a full-blown position as the final tutored son of these parents. Wherefore you are no more a servant, or a slave, or a son still being tutored, but a son, a full heir. If you are a son, and if you are in that place of maturity that adoption has placed you, then you are an heir. Many young people revel at being heir of some wealthy grandfather and wait to cash in, but believers have something far better: as believers they are joint heirs with God Himself. Les adds this is not a slip of Paul’s pen; Paul says it over and over, and it is part and parcel of Pauline doctrine. He prefers to use more than one portion rather than build doctrine on one or two verses, and he comes to Romans 8:14, where he reads, for as many, that is, all of you who are led by the Spirit of God. He notes that is exclusivist.
