<p>8:35 <i>And the servant does not stay in the house for ever. The son stays forever</i>- The Lord tweaks the metaphor a little, to argue that sinners are servants of sin; but the Lord is making us free from that servitude, turning us into freedmen, permanent members of the actual household. This metaphor of freedom from slavery is used heavily by Paul in his later explanations of the meaning of the Lord's death. A slave might spend his life in slavery within a household, but could never actually enter the family. The Son is master of the household, for ever.</p>
