The central axis is not what one might expect. He who commits sin is a slave of sin (Paul expounds on this teaching in his letters) and does not abide in the house forever, but sons abide forever. He is saying that sons are not compelled to sin – they are free (J pairs). If a son sins, it is because he has chosen to do so, not because he had no power to choose to do so or not. If you are a son or daughter, then what is the Word of God telling you? You have been set free from sin!
