Sermon: Sunday, 8th February, 2026
Speaker: John Johnstone
Scripture: Acts 18:1-17
The Christian life is often described in the Bible as a race. It’s not a short sprint but is more akin to a marathon. Like a runner in a marathon, there are times when we ‘hit the wall’. What does it mean for a runner to ‘hit the wall’? It means that all the exhaustion and pain and doubt all converge together and we hear that voice in our heads: ‘It would make sense to give up now.’ You want to quit. Why do most carry on? It’s because of the encouragements along the way, like the voice of your coach or the clapping of the crowd or refreshment at a water station. Perhaps we don’t talk about it as honestly as we should, but many are tempted to stop being involved in God’s work. Listen to the words of the great leader Joshua in : ‘Alas, Sovereign Lord, why did you ever bring this people across the Jordan to deliver us into the hands of the Amorites to destroy us? If only we had been content to stay on the other side of the Jordan!’ (Joshua 7:7)
This morning, I would like us to consider the apostle Paul, and a time he seems to ‘hit a wall’, at the start of his ministry in Corinth. We are not told explicitly that he wants to give up, but it is clear that running the race has become extremely difficult. The discouragements seem to be piling up. How will God deal with his servant? As we look together at Paul’s discouragement and then the encouragements he receives, I hope it will do 2 things- we will become more realistic in our view of the Christian life as one which is really tough, but we will also be reminded of encouragements which we can also focus on in order to help is to keep on running and serving the Lord.
1. Paul’s discouragements
We read in verse 9 that Paul receives a vision from Jesus which says to him: ‘Do not be afraid; keep on speaking, do not be silent’. This suggests to us that Paul was indeed afraid about his new work in Corinth and that he was tempted to stop the work of proclaiming Jesus as Saviour and King and was tempted to stop urging people to place their trust in him. We also remember his first letter to the church in Corinth when he writes in ch 2 v 3: ‘I came to you in weakness with great fear and trembling’. Sometimes I think we wrongly picture Paul as some kind of superhero who sure, experienced beatings and shipwrecks but just kept bouncing back up, like some kind of Weeble wobble. Do not believe it. He was an ordinary man who carried many scars of ministry. Let’s consider some of the tough things he was contending with.
First of all, there’s just the fact of how tough ministry is. Gordon Keddie: ‘Their regular hardships were the ordinary things: the long dusty miles trudging the highways of the Roman world, the sore legs, the tiredness, the sickness, the discomforts, the indifference of happy pagans, the suspicion of proud Jews, the sheer effort of going on and being faithful followers of Jesus Christ.’
There is also the place itself- Corinth. Corinth was situated on the Isthmus of Corinth, a narrow neck of land with 2 harbours, one on the east and one on the west. Between the harbours was a 3 ½ mile long road, where ships could be dragged on wooden logs. This made Corinth a hub of world trade and it grew wealthy as a result. It had a huge population; some estimate it at around 200,000 people. It is fair to say that it was a spiritual disaster zone. It was a centre for the goddess Aphrodite, the goddess of love and so there were around 1000 shrine prostitutes who would ply their trade at night. Corinth was so well-known for its sexual immorality that there was even a verb ‘to Corinthianise’ somewhere, which meant a person had lost any sense of sexual morality. Do you think it was easy ministering there? Would he not have been daunted at the thought of evangelising such people? I am sure many of us can relate to that today in our own culture which is also full of idolatry and sexual immorality. Most in Scotland do what is right in their own eyes, and not in the Lord’s eyes.
Paul must have felt spiritually jaded following his time in Athens, the place he had just left. He experienced only a little spiritual fruit there. And now he has to start afresh in Corinth on his own.
As he normally did in a new town or city, Paul began witnessing to the Jewish people. How did that go? We read: ‘4 And he reasoned in the synagogue every Sabbath, and tried to persuade Jews and Greeks. 5 When Silas and Timothy arrived from Macedonia, Paul was occupied with the word, testifying to the Jews that the Christ was Jesus. 6 And when they opposed and reviled him, he shook out his garments and said to them, “Your blood be on your own heads! I am innocent. From now on I will go to the Gentiles’.
Paul is a man who has met the risen Jesus and whose life has been transformed by him. In love, Paul wants to reach his own people the Jews and tell them about Jesus. That’s why we want to tell our friends about Jesus! However, he faces great opposition and resistance and this is not an easy thing to deal with. Paul makes the dramatic gesture (v6) of shaking the dust off his clothes, a sign that he was not responsible for their hardness to the message of Jesus and that their blasphemous response would have serious consequences. It is so discouraging when preachers preach and see very little change in people’s lives, whether in terms of conversions or direct opposition to the gospel.
Remember too that Paul is working as a tent-maker through the week and so he must have been physically exhausted combining a 9-5 job with the weighty task of evangelism. This also suggests Paul might have run out of money and so was forced to work on two fronts at once.
All of these discouragements remind us that the Christian life is far from easy. It is a battle. We need to expect discouragement and when we talk to people about Jesus, whether at home, work or in the community, we need to expect opposition. This is normal and should not catch us by surprise.
It would be easy for us to look out at Fife and see the 99% of people who do not know Jesus and just feel like giving up. Here’s a question to help us as we think about that. How did God view Corinth and how does God view Fife? Does he just see a place of moral darkness that we should just forget about? V10 is a window into the heart of God: ‘I have many in this city who are my people’. There were many in Corinth and in Fife too who have an inner yearning to know who God is and how we can get to know him. They long for meaning and purpose in their lives. And ultimately, this meaning and purpose come from the gospel. And God is determined to seek them out and find them. And God is going to use Paul to reach them. He will use us to reach Fife. This is how God works.
2. The encouragements which keep Paul going
We all need encouragement in our work. Even Jesus did. At the start of his ministry, God the Father encourages him at his baptism, telling him: ‘You are my Son, whom I love; with you I am well pleased (Mark 1 v11).’ Paul needed encouragement and we too need it in order to keep on going. How does the Lord encourage Paul here?
Encouragement through friendship. Although arriving in Corinth alone, the Lord provides Paul with work, a place to live and also deep and meaningful friendship with Aquila and Priscilla, with whom Paul becomes partners in ministry. We cannot underestimate this. Even more than that, Silas and Timothy arrive from Macedonia, probably with a financial gift enabling Paul to give up his tent-making and focus on preaching and teaching. Perhaps there is a principle here that Christian workers are not meant to be on their own. After all, when Jesus sent out the 72 we read in Luke 10 v1: ‘After this the Lord appointed seventy-two others and sent them two by two ahead of him to every town and place where he was about to go’. I am so pleased there’s a core team in Leven Free Church, and that it is not just Geoff on his own. We should not be isolated in ministry.
The Lord also encourages us with gospel fruit. When Paul moves away from his ministry in the synagogue he does not stagnate; he moves next door to the home of Titius Justus. He now has a new ministry base. God wonderfully works in the life of Crispus, the synagogue ruler, and his family.
And there is more! We read (v8): ‘…many of the Corinthians who heard Paul believed and were baptised’. These are same people who were so tangled up in sexual immorality and idolatry. But God is merciful. God is clearly at work. We can also see these things today in our own churches. God has saved people in this church and in Leven- someone in Leven even in the last few days. God is at work. This really does put a spring in our step and reminds us that God is changing people.
But the greatest encouragement in this passage has to be the timely vision which God gives to encourage Paul to keep going in the work (vs 9-10): 9 One night the Lord spoke to Paul in a vision: ‘Do not be afraid; keep on speaking, do not be silent. 10 For I am with you, and no one is going to attack and harm you, because I have many people in this city.’
God promises Paul his presence. I will be with you. This is the greatest promise any of us can have. But is this promise just for Paul? No! It is for all Christians. Hebrews 13 vs 5-6 speaks to all Christians, whatever their situation might be: 5 Keep your lives free from the love of money and be content with what you have, because God has said, ‘Never will I leave you; never will I forsake you.’ 6 So we say with confidence, ‘The Lord is my helper; I will not be afraid. What can mere mortals do to me?’ And we know that Jesus promises at the end of Matthew, that as ordinary people like us make disciples, we go and share the gospel with this promise: ‘19 Therefore go and make disciples of all nations…And surely I am with you always, to the very end of the age.’ Does that encourage you?
Many people want to shut Christians up about Jesus. They say again and again ‘there is no such thing as truth, just your truth’. But that absolute statement is wrong in itself. Some will talk about any taboo subject, but will not discuss the gospel. But many others are willing to speak about these things. God says to us today: ‘Do not be afraid; keep on speaking, do not be silent’. He wants us to tell others just how much Jesus has done for us. And when we face hassle and opposition (and we will) he promises to be with us. That ought to give us confidence and resilience as a church family. He wants us to open our Bibles up with people who do not know the Bible and chat with them. We cannot do this on our own strength, but we can with God with us. Keep praying for people and keep talking with people about the Lord.
Let’s end with the thrilling promise Paul receives (v10): ‘..because I have many people in this city’. God is encouraging Paul by revealing to him many people are going to become Christians, even in this decadent city. God will do it and he will use his people. Paul now knows he will not be killed or prevented from preaching in Corinth, because it is God’s plan to save many people there. And that is exactly what happened. This promise energises the discouraged and tired apostle, giving him renewed zeal in his gospel labour. It reminds me of Jesus’ words in John 10 vs 27-29: ‘27 My sheep listen to my voice; I know them, and they follow me. 28 I give them eternal life, and they shall never perish; no one will snatch them out of my hand. 29 My Father, who has given them to me, is greater than all; no one can snatch them out of my Father’s hand’.
Does God say to us today: ‘I have many people in Fife’? I don’t think that is a stretch. I believe that there are many people in Fife who belong to the Lord, but do not know it yet. God might well use us, through our prayers, through our example and through our words (all 3 things) to bring them to faith. Jesus promises that some of the seed will fall on good soil and grow. The LORD promises Abraham that his spiritual descendants will be as numerous as the stars in the sky. What does this mean for us? It means that there are people waiting to hear the gospel, and when they hear it, God will awaken them. Ask Martin in Leven as it just happened to him. Ask Daniel who was here in KFC. God uses our prayers and uses our witness. Let’s keep going in sharing Jesus with an expectation, an expectation that God will save his people. What an encouragement!
