Sermon: Sunday, 24th November, 2024
Speaker: John Johnstone
Scripture: Romans 6:15-23
God’s law sometimes gets bad press, even in Christian circles. This is partly because the purpose of God’s law is misunderstood, or should I say purposes (plural). That’s the thing about God’s law. It has several different functions. It reveals God’s character to us. For example, when we say, ‘Do not lie’ that’s because God is a God of truth. It also functions like an x-ray of our hearts, because when we read the 10 commandments, we are meant to think, ‘I actually haven’t kept any of those.’ So, the law is meant to show us our sin, and in doing that, it sends us to Jesus the Saviour we need.
But another function of the law is to give Christians freedom, in that it shows us the way God wants us to live. God’s laws are designed to give us freedom. For example, imagine there were no traffic laws and you could drive without any rules. Would that be freedom? Of course not. It would be harmful to us, not to mention other drivers. If all drivers stuck to the rules of the road, driving would be safer and more enjoyable. The same is true of God’s laws. God’s people are called to obey them, not to cramp our style, but to bless us. They show us the way of love and true freedom. Do you have a positive attitude to the law?
However, if God’s laws are so good for us, why does Paul say that Christians ‘… are not under the law, but under grace.’ (Romans 6:14) It would be easy for us to misunderstand what Paul is saying here. What does he mean when he says we are not under law? He means that we cannot get into a right relationship with God by obeying the law, summarised in the 10 commandments. The law is not a ladder we need to climb and climb in order to get to Heaven. He means that as Christians, the judging and condemning power of the law no longer has a hold on us, as in Christ we are forgiven. Because of God’s grace, we are treated as if we had never sinned. We cannot climb up to Heaven, but in Christ, God has come done and kept the law which we could never keep, and died on the cross to remove the curse of the law from us.
However, we must not go too far. Some people read verse 14, and when they hear that ‘we are not under the law’ they wrongly assume that the law has no place in the Christian life. They think that we don’t really need to try and keep the law. This is not true. Whilst we cannot earn God’s forgiveness through keeping the law, once we are saved by God’s grace, we are given the Holy Spirit in order to help us to keep the law. We keep it not to earn brownie points, but out of gratitude to the God who has saved us. RC Sproul once said: ‘The essence of the Christian ethic is gratitude.’ This is so true. All Christians ought to conscientiously keep God’s law out of a response of gratitude to how much Christ has done for us. So, we are not under the condemnation of the law as Christians, but we must still keep all his laws, motivated by gratitude. We must understand that keeping God’s law out of gratitude to God is the way of freedom and blessing.
As we saw last week, some people heard the gospel and twisted its teaching saying that Christians might as well live any way they choose, ignoring God’s law – after all, God will just forgive us anyway. Some even wickedly argue that the more we sin the more God’s grace is displayed, and so we should sin as much as possible. Paul has already strongly opposed this false teaching, arguing that Christians are people who are in union with Christ and have died to sin, and received Christ’s life-giving power. Sin has no place in our lives. We are new creations. We are new people. We are ‘dead-to-sin’ people. We cannot continue in sin because of what God has done for us – joining us to Jesus Christ.
1. You have a new master
In verse 15, Paul returns to this twisted thinking: ‘What then? Shall we sin because we are not under the law but under grace? By no means!’ Some people, even some Christians might have a careless attitude to sin. We slip into thinking, ‘What difference will this little sin really make? God will understand.’ We might fool ourselves into thinking that we can ‘play with sin’ as if we are in control of sin, and can go so far, but will be able to stop when we want to. That is not how sin works. The Bible speaks of ‘… the sin that so easily entangles…’ (Hebrews 12:1) It’s like an octopus with its tentacles around us.
Once again, Paul gives another reason why Christians can never treat sin lightly. The reason is this: when we became Christians, we pledged our allegiance to Christ. He is our master now. ‘Don’t you know that when you offer yourselves to someone as obedient slaves, you are slaves of the one you obey…’ (Romans 6:16) If we are slaves to Christ, and we are, then we must obey his commands. We are no longer slaves to sin. Our allegiance has totally changed.
At first, this might sound shocking. You might even think, ‘I’m a Christian but I don’t want to be a slave to anyone, not even Christ.’The word ‘slave’ almost always carries negative connotations for us. But not here. Think of the very first words in this letter. ‘Paul, a slave of Christ Jesus, called to be an apostle…’ (Romans 1:1) Paul identifies as a ‘slave’ of Christ. This is not all Paul says – for example he also identifies as an adopted son of God and an heir with Christ, in chapter 8. God is our Father and we are his children.
Nevertheless, we need to grasp what we mean when we say that we are ‘slaves’ of Christ. It is a voluntary slavery! In Roman times, around a third of the population were slaves, and many others had been slaves and so around half of those Paul is writing to know what he means. It was commonplace for people in severe poverty to offer themselves into slavery, so that they could guarantee they’d have a roof over their heads and food on their tables. If you surrendered yourself as a slave, then of course, you had obligations to fully obey your new master. Everybody knew that. ‘Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness?’ (Romans 6:16)
Christians are people who voluntarily pledge themselves to be servants or slaves to King Jesus. We present ourselves to him as his slaves. The only other alternative is to present ourselves to sin, and be slaves to sin. There is no other option. The thing is, to be a slave to Jesus, to pledge our allegiance wholeheartedly to him is true freedom. Don’t get too worked up about the language of slavery – Paul is just using it as an illustration. The point is this, the hallmark of slavery is obedience, and those who pledge allegiance to Jesus must obey him. We are not free to do a little sinning on the side.
John Stott: ‘Conversion is the act of self-surrender; self-surrender leads inevitably to slavery; and slavery demands a total, radical, exclusive obedience. For no-one can be the salve of two masters as Jesus said. So, once we have offered ourselves to him as his slaves we are permanently and unconditionally at his disposal. There is no possibility of going back on this. Having chosen our master, we have no other choice but to obey him.’
This is a helpful reminder that becoming a Christian, or conversion, is when Jesus becomes both our Saviour and also becomes our Lord or master. You can’t have Jesus as just your Saviour and then live any way you please.
You might find this teaching of Paul offensive. Do we really either have to be slaves to sin or to Christ? Can’t we be neutral? In Jesus says; ‘Very truly I tell you, everyone who sins is a slave to sin. Now a slave has no permanent place in the family, but a son belongs to it forever. So if the Son sets you free, you will be free indeed.’ (John 8:34-36) We cannot be neutral. We cannot remain slaves to no one, even if we think we can. All humans are by nature those who serve themselves. We can be slaves to our work, pouring ourselves into work and living for it. We can be slaves of our possessions, always wanting more stuff, the latest gadgets and more new clothes. We can be slaves to all kinds of negative habits, such as being bad-tempered, greedy, or lustful. We are prisoners of our appetite to sin. We cannot escape sin or its penalty, which is death.
Kent Hughes: ‘Characteristically, the most enslaved argue that they are the most free’.
Think of the prodigal son, who felt so free as he headed off to the far country. Was he really free? Of course not!
2. You have a new lifestyle
Verse 19 highlights to us that being a slave to sin is not something static, but is a downward spiral. In contrast, being a free slave of Jesus Christ leads to a virtuous upward spiral on the path of holiness: ‘For just as you once presented your members as slaves to impurity and to lawlessness leading to more lawlessness, so now present your members as slaves to righteousness leading to sanctification.’ In other words, in the past you used to use your energy to serve yourself; now, use your energy to serve Christ.
What does it mean to ‘present our members as slaves to righteousness’? It is comprehensive. It means to use our hearts and minds and hands and feet and gifts and talents and all that we are and yield them to Christ.
A well-known hymns puts it like this:
1. Take my life and let it be consecrated, Lord, to thee…
2. Take my hands and let them move at the impulse of thy love…
4. Take my silver and my gold; not a mite would I withhold…
5. Take my will and make it thine; it shall be no longer mine…
Paul states it memorably; ‘I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.’  : (Romans 12:1) Living as a Christian involves a radically new lifestyle. We were pleasers of self and now we are driven, albeit imperfectly, to please God.
Think back to before you were a Christian. Perhaps you were single-minded in climbing the career ladder, or getting more money, or enjoying yourself as much as possible with good holidays, food, wine and experiences. Our pursuit of holiness should be just as dedicated as that. And this single-mindedness doesn’t make you a fanatic, nor does it mean your life will be impoverished. You will not be the loser. In fact, as the end of verse 19 says so clearly, yielding to righteousness leads us to become more like Jesus – it is for our sanctification. Just as fish are made for water and birds to fly, so we are designed by God to be most free when we live for his glory.
St Augustine said that all human beings are like a horse, and the horse has one of two riders. Either Satan or Christ is riding the horse. Before conversion, Satan held the reigns to your horse, and you were free (verse 20) in regard to righteousness, which means you were enslaved in darkness. Now, Christ has your reigns, and he leads us to beautiful places. Who would you rather have in control of your life? Who do you want holding your reigns?
3. You have a new destination
What was our destination before we trusted in Jesus? Verse 21 says the end of slavery to sin is death. We know it leads to separation from the goodness of God. Paul wants us to think back to our pre-Christian days and to realistically consider what our sinful actions produced. We might have enjoyed sexual immorality for a time, but in the end, it ruined a marriage and a family and brought intense suffering to many. The fruits were dark. You used to spend so much of your money on yourself without a thought for others. Did it satisfy you in the end? No. Sin promises much but delivers so little. It’s been that way since Satan told Adam and Eve they would have knowledge through disobeying God. Sin destroys our relationship with God, with others, and even prevents us from being our true selves, the people God intended us to be. Sin is a terrible master every single time. There is one thing which sin the slave master will always do – he always pays us fair wages. The thing is, the wages of sin is death (verse 23). And this is what we deserve by refusing to yield to Christ.
But it doesn’t have to be that way. There is a wonderful alternative. Those who are slaves to Christ and to righteousness are not given wages. Instead, we are given a free gift, and that gift is eternal life. ‘For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.’ (Romans 6:23)
What do you want from God, the wages you deserve or his free gift?
