What Dr Guy Waters argued that the “Life giving Spirit” of second Adam who is Christ, seems to be confusing. There is always the distinction between the Holy Spirit and the Spirit of Christ. However, he argued from: Romans 8:9–11
9 Anyone who does not have the Spirit of Christ does not belong to him…… 11 If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.
Paul talks about the Spirit of Christ dwelling in us, (Rom 8:9) and v11 says the Spirit of God (Holy Spirit) who raised Jesus from the dead dwells in you, this is clearly saying the Spirit of Christ is the Holy Spirit. Waters argues that Paul is not erasing the distinction between them, but making an economical or functional identification of Christ and the Spirit. The bodily resurrection of Christ has secured and bestows him upon his people. I do like the combo effect of the Spirit of Christ and the Holy Spirit, at least, in terms of economic function. And I agree.
1 Cor 1:7 “…so that you are not lacking in any gift, as you wait for the revealing of our Lord Jesus Christ,” This is spiritual gift from the Lord. Paul writes that “ …because of the grace of God that was given you in Christ Jesus, “5 that in every way you were enriched in him in all speech and all knowledge.” Through the grace of God in Christ, we the believers have been enriched, or I call it empowered, in Christ in all speech and knowledge (1:4). That’s one huge promise of God, hard to fathom we ever have all that. But in harmony with other verses like growing in maturity to be more like Christ, we know that that “enriched” is a gradual process. The important point that’s the gift of the Spirit. V7 says we don’t lack any gift as we wait for the revealing of our Lord Jesus. These all point to the thesis that the resurrection of Christ is the “Life giving Spirit” that enriched us, and empowered us, and granted us the grace of God so we lack no gift!
Because these spiritual gifts are a result of Christ’s resurrection, therefore they are the resource through the gospel, to combat the wisdom of the world. It’s important to realize that the resurrection of Christ not only brought us salvation, justification and adoption, but also actually helping us to fight against the corruption of the world and our sinful self. This is a big point I want to highlight, so all that is achieved by Christ’s resurrection goes beyond just redemption, but also sanctification, glorification. In this broken depraved world, Christians combat the rottenness of the powers of darkness, temptations to sins, and also the discouragement by the barrage of sinful and abominations displayed blatantly in the eyes of God and the church. And Christ’s resurrection causing the imputation of the Holy Spirit literally empowers us, and strengthens us to fight against these fleshly divisions and factions and brokenness we see in the Corinthian church, and definitely in today’s churches too.
