Summary: Paul says, "If anyone does not have the Spirit of Christ, He does not belong to Christ." We must possess the Spirit to be possessed by Christ. He must be ours if we are His. Mutual possessing and mutual indwelling is what salvation is all about.

Indwelling has a variety of meanings. It can mean that matter indwells matter as a kernel or

fruit within a shell. A yoke indwells the white and both dwell within the shell. It can refer to a

situation where one substance is intermixed with another, as with salt and water, or medicine

within your blood system. Then there is the non-material indwelling the material. When an artist

really puts himself into his art, we say his spirit indwells it. A musician lives in his composition.

It reveals his nature, personality, or mood.

This is what we mean when we say God indwells His creation. His beauty and harmony of

nature are built right into what He has made. Another type of indwelling is related to heredity.

Parents indwell their children in the sense that part of them has been reproduced. Man being

made in the image of God conveys this idea, and so God indwells men in the sense that they have

qualities that are from His nature. We can speak of one man dwelling in another in the sense of

influence or inspiration. If a man is a follower of another's methods or ideas, you can say that he

just lives in that man.

All of these ideas of spiritual indwelling fit the meaning of being indwelt by God, but they all

fall short of the full meaning. Paul makes it clear in this passage that God's indwelling is not just

figurative, and does not just relate to His image, influence, and inspiration, but to a literal

indwelling. God actually abides within our literal flesh just as Jesus literally entered the flesh of

a human body in the incarnation. The term Christian refers to those who are Christ ones, and that

is what we literally are as Christians. We are little Christ's. We have the same Holy Spirit

indwelling us as He had. The source of His wisdom and power is within us as it was in Him. In

verse 11 Paul makes it clear that the very Spirit of God who raised up Christ is the Spirit that

dwells in the believer, and it is He who will also raise us up to life immortal.

It is no wonder that Paul was such a man of assurance and certainty. Paul didn't claim to

know everything, for he said that we know only in part. Much was mystery to Paul, but he was

sure of the indwelling of the Holy Spirit. We want to study this passage verse by verse in order to

grow in the knowledge that is necessary to have the assurance of Paul.

In verse 9 in the KJV Paul says to the Roman Christians, "You are not in the flesh." If you

take this literally you would think Paul was writing to disembodied Christians. It sounds like a

weight watchers paradise. But the modern versions make it clear that Paul is saying they are not

controlled by the sinful nature. He is saying that the natural man is not controlled by the Spirit,

but the Christian is to be so controlled. Those who are in flesh live their life with no regard for

God and His will. They live in a sphere that is flesh controlled and dominated. In contrast Paul

says the Christian is controlled by the Spirit. Paul's method of getting people to examine

themselves is far superior to that of asking people

if they are saved. Instead of asking them, he describes the two spheres in which all people live,

and then let's them judge for themselves which sphere they are in. To be in the Spirit is the

opposite of being in the flesh. If you are in the Spirit and controlled by the Spirit God will play

the dominant role in your decisions, thoughts, and acts. John wrote in I John 14, "Hereby we

know that we dwell in Him, and He in us, because He has given us of His Spirit." The indwelling

Spirit is the key to Christian assurance.

Then Paul says, "If anyone does not have the Spirit of Christ, He does not belong to Christ."

We must possess the Spirit to be possessed by Christ. He must be ours if we are His. Mutual

possessing and mutual indwelling is what salvation is all about. These are terms that are not

familiar to us because we have taken a few biblical concepts to describe salvation and have

ignored the rest. This is a statement of absolute finality, just like the statement, "You must be

born again." You must have the Spirit of Christ is saying the same thing. Having the Spirit is a

good biblical phrase that we ought to use, for it means to be a child of God. We tend not to use

this terminology because it brings the Holy Spirit into the center of the plan of salvation, and we

tend to be weak in our understanding of the role of the Holy Spirit.

In verse 10 Paul says, "But if Christ is in you...," and so we see that Christ in us, the Spirit of

Christ, and the Spirit of God, are all used interchangeably. They are one, and you cannot have

one Person of the trinity in you and not have the others. Where one is, all are. Then Paul says

your body is dead because of sin. What does this mean? Does Christ dwell in a corpse? Was He

resurrected and ascended, and then sent back to dwell in dead bodies? What Paul means is that

the body of the Christian is subject to death. It is in the realm of the dying, and will return to dust

because of sin.

In other words, the Christian is only partially saved in the present. Sin still has power over the

realm of the flesh, and as Paul goes on to say, not until the resurrection will our bodies be made

spiritual and enter into the realm of the Spirit and be saved. Christians, therefore, are half and

half. They are half saved and half not saved, but the half not yet saved has a guarantee to be

saved if the Spirit indwells them.

Then Paul ends verse 10 by saying, "Yet your spirit is alive because of righteousness." It is

alive because of the righteousness of Christ. Jesus said, "He that believes in me, though he were

dead, yet shall he live, and whoever lives and believes in me shall never die." The Christian is

alive even if he is dead. Death no longer has dominion over them. The body which is still subject

to death is not the controlling factor in the Christian. His body does not run the show as it does

for those in the flesh. For the Christian the Spirit is in control, and so the power of the

resurrection is already in operation in the Christian life. The resurrection life is a life in which the

Spirit is in control, and not the body. There is no difference between the bodies and the lost and

those of the saved. The difference is in the Spirit. The spirit of the lost man is a slave to his body,

but the spirit of the saved is a co-partner with the Spirit of God.

In verse 11 Paul makes it clear that sin and death will not gain the slightest victory over the

children of God. He wants to make it clear that though the body is dead and not in control it is

not to be abused, for it will be a part of the total plan of salvation. Jesus indwelt a body, and even

though it died it saw no corruption. God will not let any body He has dignified by His in

dwelling be left in the grip of death. All that God indwells shall be eternal and so if the Spirit indwells us,

we can have perfect assurance of immorality. Just as certain as Jesus rose with a body changed

and made immortal, so shall all Christians rise and be changed. The power of the resurrection is

the power of the Spirit, and no temple of the Holy Spirit will lie forever in the dust, for the Spirit

will give life even to our dead bodies.

In the light of all that the Spirit does for us now and for eternity Paul goes on to say that we

have an obligation to live according to the Spirit and not according to the flesh. We do not owe

the body anything, for its fleshly nature only brings us down, but we owe the Spirit everything,

for He lifts us up to the dignity of being God's child.

Paul goes on in v. 13 to say that we will die if we live according to the sinful nature of the

flesh, but we will live if we put to death the deeds of the body by means of the Spirit. This is life

now and forever. We must be in constant battle with the body to keep it under the control of the

Spirit. We must present our bodies as living sacrifices as Paul says in chapter 12 of Romans. We

must die daily or the body will dominate us and lead us in many ways that are not truly life, but

paths to death. The spirit is willing but the flesh is weak, and if you let your body determine what

you will do, it means you will do much less for Christ and for your own spiritual growth than is

you are controlled by the Spirit. The flesh will keep you from doing much that is God's will for

your growth.

By the grace of God the Spirit working with our spirit can overthrow the tyranny of the flesh

and reign in its place. The Spirit can gain control and discipline the body and bring it under

submission. This will lead to the fruit of the Spirit being produced in your life. The Spirit will

help us put to death the desires of the body to be lazy and indifferent to the things of God, and the

desires to do what is contrary to the will of God. If the Spirit is not in control, the body will

quench the Spirit and we will be carnal and not spiritual. Something has to die, and it is either the

flesh or the Spirit, and which it is determines the quality of your life now and for eternity.

Assurance of salvation; assurance of eternal life, and assurance of abundant life now are all

dependant upon the indwelling of the Spirit of God.
