God’s Happy Slaves (Romans 6:15-24)

We’re discovering what it means to live in the amazingly generous life that God provides for us in his Son. For some, this raises questions. In particular, how seriously does a Christian need to regard sin in his or her life?[i]

In the previous section, Paul showed us that God has placed us wholly in Christ and in what he has accomplished[ii]. And he does this so we are able to live an entirely new life, and so our sinful propensities may be disabled.[iii]

And now, Paul asks the question again. ‘Are we free to sin?’

He has just said we’re not ruled by law. God’s law is no longer in a position to condemn us. Does this mean we can sin without consequences? If there’s no road rules, can we just do whatever we like?

As with the first question, Paul responds with some horror. ‘May this never be!’ Such a thought would cancel belief in a good God, or human responsibility or a moral universe. Unfortunately, much of the world embraces these ideas. And the results are clear. Total chaos.

Rather, we are shown what it means to be under the control of grace! This is what Paul knows personally, and he’s seen it work out in the lives of many new believers.

And every converted person knows it too. ‘Don’t you know…’ Paul says. Sin had enslaved us. Now, righteousness—that is, justification—rules us. We have a new master.

Is this the truth we know? Not just forgiveness—a life wiped clean of every impurity, but righteousness—God’s final judgement revealed in advance. If we understand this, we can’t live without it. We are ‘slaves’ to this new identity.

Paul knows that slavery isn’t really what Christian faith is like, but it’s like it in the ways he describes. And he’s happy to identify himself as Christ’s slave at the beginning of his letter.

And here’s what undergirds this. When the gospel is preached, we become obedient from the heart to what we are hearing.

We don’t just give assent to an idea. To believe it is to obey it. That’s why Paul talks about ‘the obedience of faith’ later on.[iv] The gospel itself brings about this obedient faith.

Paul uses an unusual phrase to describe how the gospel comes to us. It’s a ‘standard of teaching’. It’s not just another lesson to learn. It’s God, speaking—to us. The word suggest that it’s imprinted on us.  God knows how to speak to those he calls. When he forgives our sins, he writes his law on our hearts. He gives us a new heart.[v]

And we are ‘entrusted to’ it. In other words, God doesn’t trust us to believe his gospel. He entrusts us to his gospel and the gospel does the job he wants it to.

This gospel teaching leads us to righteousness. And in this context, righteousness is God’s gift[vi]. We are justified. But, as anyone who is justified knows, it’s liberating to be clean and at peace with God. Righteousness is a good way to be. We want righteousness.

Here’s Paul’s opportunity to show that the news of God’s goodness is precisely the way he brings us to living well—to be his happy slaves.[vii] He’s led us out of sin, not freed us up to enjoy it.

So now, we need to choose which master we will serve—sin or righteousness. There’s no real freedom that isn’t related to an authority. We make this decision when we believe in Christ, but it’s a decision affirmed with each new day—to present ourselves to God for his service. This is what Jesus did as God’s suffering Servant.[viii]

In one sense, knowing what to do when sin is pressing for attention is simple. Run from it! Joseph is a good example.[ix] But we’ve got more resources than just running. We have powerful reasons for our choices. And there’s a wonderful reward.

Sin, contrary to entertainment promotions, is not nice! It comes with an agenda of its own—and we are its victims. We used to give ourselves to thoughts and deeds that God says are wrong. Paul gave us a list of them earlier in his letter.[x]

We had an illusion of freedom because we felt free of any external demand. But sin has a destination in view. It wants us dead. Or, more accurately, he—Satan, wants us dead.

And sin pays wages. In other words, we get what we deserve.

Now, contrast this with being obedient.  We give ourselves to Christ who loves us. We trust him and are pronounced righteous. And righteousness becomes the desire of our whole being. Jesus teaches us that those who hunger and thirst for righteousness will be filled—filled with righteousness.[xi]

So—and here is the only command in this passage—give all you’ve got to this ‘standard of teaching’![xii] It will lead you on to sanctification—that is, actually living as one devoted to God. You’ll increasingly want and be doing God’s will on earth, just as it is in heaven.

And then, you won’t get what you deserve! Who would want to live with this hanging over their head? Rather, you will receive a gift. Eternal life—in Jesus Christ our Lord.

So, living under the reign of God’s grace is not a free ride into irresponsibility. Neither is it an impossible journey of committing and recommitting ourselves to obey an unrelenting law. It’s trusting and enjoying and living in the amazingly generous decision of God to receive us as his righteous people. We’re happy to be his slaves. It’s here that we’ve found freedom.

We’re alive—because of the Holy Spirit (Rom. 8:1-17)

We’ve come to the part of Paul’s letter to the Romans where he tells us how ‘new life in the Spirit’[i] actually happens. In other words, this is how to live as a Christian. We belong to Christ because we have received his Spirit.[ii] That’s our new life. And now, we are to continue as we began.[iii]

We need to know what God has done (vv. 1-4), what has happened to us (vv. 5-11), and what we should do (vv. 12-17).

What God has done begins with him not condemning us. There’s no other starting point for us sinners. Those who try to stir us to action by making us feel guilty (what the world is doing all the time) are doing devil’s work, not God’s! And those who punish themselves to generate more effort will probably give up eventually. God has no other way to have people doing his will than by beginning with no condemnation.

What God has done is to send us his Son. He gives him a body like ours—not sinful as our flesh is, but like ours so that he can feel the effects of what sin does. He bears our sin. God condemns our sin, in his flesh. That’s why there’s no more condemnation of us. To ignore this, or work around it, is not only ungrateful and unbelieving. It’s useless.

And then God sends his Spirit—as life itself. He is nothing less than the outpouring of God’s love.[iv] And he hasn’t come as a mood changer. He’s come to be our Helper—as Jesus was to the disciples when he was physically present[v]. He enables us to know God and his salvation. And he also teaches us to love God and his will, and enables us to live in tune with that. We’re under a totally different regime[vi].

In this way, and no other, God has done what his law couldn’t do. Now, we will truly fulfil the righteous requirement of his law.

Our obedience in this life is never complete. But it’s real. And the blood of Christ cleanses all our sins—as they happen[vii]. Condemnation never gets a look in.

God doesn’t rescue us just to toss us back into the mess we made of our lives. And freedom is not choosing our own life style! It’s being liberated from condemnation and doing what we are created to do.

This is a massive claim and we need to know how it works out.

So, we look at what has happened to us.

What God has done means that there are now two kinds of people. There’s Spirit people as described above, and flesh people, meaning everyone ese.

What’s important to flesh people is things that can be seen, controlled and indulged—and certainly not God or his commands. There’s no way they are going to spend their lives pleasing God. But to choose this is to choose death—walking.

What’s important to Spirit people is what the Holy Spirit reveals and does. This way is life and peace—as we have already seen[viii].

Paul is confident that people reading his letter belong to this latter group—people like ourselves. The work of the Spirit in our lives is evident. He is creating new life in us—and all because we are justified—righteous in God’s presence.

We belong to Christ. Christ has come to us and lives in us. And even though we are still sinners (remember chapter seven!), and going to die, the Holy Spirit who is given to every believer, guarantees we will be raised from the dead—like Jesus.

With a life like that, isn’t that what you would set your mind on?

So then, what should we do?

If we’ve understood the gospel as God’s power[ix], and God’s grace[x], and God’s presence and God’s future—not just an ideology, we’ll know that we owe our old life nothing!

Rather, we owe everything to this beloved Holy Spirit. This is short-hand for saying we owe everything to what he has brought to us—God and Jesus and righteousness.

If we now set our minds on this, and if we say ‘No!’ to our miserable former selves, we will have life from God.

Look at it! We’re God’s children! His Holy Spirit doesn’t just rely on the psychology of gratefulness to make us obedient. He forms in us the same cry he formed in Jesus—‘Father!’ And, like him, we want to do our Father’s will. We’re happy to be slaves of Christ but don’t feel or act like slaves. There’s no anxious fear here!

And being part of this family has a future. We’re going to share with Christ in the family inheritance. There’s some suffering to endure—and Paul is going to talk about that in a moment. But if we set our minds on what the Spirit is about, we’ll share in the coming glory with Christ.

Every day, we will need to ask ‘What is important in this moment of my life? Where is my life coming from?’ What will be important when this coming day arrives? And every day, we will need to answer, ‘I’m going to listen to the Holy Spirit’.
