Rom. 8:8 So then they that are in the flesh cannot please God. 9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. There are only two kinds of humans between Genesis 1:27 and Revelation 22: 1. Saved versus lost 2. Children of God versus Children of wrath (Satan) 3. "in the flesh" versus "in the Spirit 4. regnerated or unregenerated 5. Elect or non-elect 6. Beleivers or unbelievers The New Testament promise of indwelling by the Spirit does not have anything to do with INDIVIDUAL indwelling by the Spirit of God but with CORPORATE indwelling (plural "you") as the new "house of God" as an institutional congregational body (1 Cor. 3:16). The Spirit still comes "upon" the saved and leaves them in the very same sense He did between Genesis and Acts 2:1. Empowerment! The Spirit has always been "with" indivduals in the sense of personal indwelling, sealing, regeneration, santification, etc. But he has never been "in" a plurality of persons as one institutional body or temple because the temple of God has never before been composed of "lively stones built up a spiritual temple" (1 Pet. 2:5; 1 Cor. 3:16; 12:27). Man has always had the SAME problem - sin God has always had the SAME solution - redemption in Christ no redemption outside of Christ for anyone at any time. Salvation has always been the same - divinely purposed in Christ before the world began - Christ coming and providing for redemption - gospel proclaiming either he is coming or has come - regeneration/conversion/circumcision of the heart - justification/adoption - progressive sanctification by the indwelling Spirit and eventually glorification. The Law was "ADDED" merely to emphasize the gospel as GOOD news through revealing sin and utter inability to be justified by anything man can do for God. The Old Testament house of God was the public administration of God's kingdom on earth prior to the coming of Christ. The New Testament house of God is the public administration of the kingdom on earth presently. The Old Covenant or "do this and live" was established in the Garden (Gen. 2:16) as was the New Covenant (Gen. 3:15) but the institutionalization of it and public confirmation was by Moses whereas the intitutionalization of the New Covenant and public confirmation was by Christ and both were ratified by blood. The gospel has always been the same (Heb. 4:2) with the exception that prior to the cross it was progressive in revelation looking to the cross whereas now it is prophetic in fulfillment looking back at the cross but the same Christ (Acts 10:43) the same way, the same covenant (Heb. 13:20) and the same salvation (Jn. 14:6; Acts 4;12). Here is the key to understanding salvation revealed in scripture. There is no salvation OUTSIDE of Christ for anyone at any time between Genesis and Revelation (Jn. 14:6) and all mankind between Genesis and Revelation who do not have the indwelling Spirit of Christ are "none of his."
