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 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? God is calling us righteous. If we understand this, the freedom and joy of it, 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. Sin doesn’t have dominion over us anymore. That’s what Paul has already shown us. And if we trust in Christ, we become obedient to his new regime of righteousness. 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 obedience.
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. And Paul will tell us in his next section that he loves God’s law.
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 isn’t nice! It comes with an agenda of its own. It wants us as its victims.[x] 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.[xi]
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. 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.[xii]
So—and here is the only command in this passage—give all you’ve got to this ‘standard of teaching’![xiii] 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 if that’s not happening, we’re not comprehending Christ’s victory over our sin. We need to go back to the beginning of this chapter and read it again! We need to pray for our stubbornness to be overcome!
And then, if we live in this imprinted teaching, we won’t get what we deserve! Who would want to live with this hanging over their head? Rather, we 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 find our freedom.
