But you are not in flesh, but in (en) Spirit, since the Spirit of God dwells (oikei) in you. But if anyone has (echei) not the Spirit of Christ, this one is not His. But if Christ is in (en) you, the body indeed is dead because of sin, but the Spirit is life because of righteousness. But if the Spirit of the One having raised Jesus from the dead dwells (oikei) in you, the One having raised the Christ from the dead will also make your mortal bodies live through the indwelling (enoikountos) of His Spirit in you. (Romans 8.9 – 11)
Locations of ‘oikei’:
•Romans 7.18
•Romans 8.9, 11 (Spirit of God dwells)
•1 Cor 3.16 (Spirit of God dwelling)
Locations of ‘enoikountos’:
•Romans 8.11
•2 Tim 1.14 (Holy Spirit dwells)
Romans 8.9 – 11 informs the reader that The Holy Spirit (Spirit of God) is separate from the Spirit of Christ by employing entirely different verbs in their description.
The Holy Spirit uses the verbs, ‘oikei’ & enoikountos’, meaning that a ‘cohabitation’ event is occurring. This is a literal Person-to-person event. The Holy Spirit resides within a person.
Contrasted to this is the Spirit of Christ, which is promoted via the preposition ‘en’ (in), and the verb ‘echei’, to have or hold.
