The gospel the apostles taught is preserved in Luke’s account. The Holy Spirit they relied on is with every believer. We should have the same confidence. How is the church going to grow? There are three scenes in this passage. We can have full confidence because God is building the church on the foundation of his word.
When Christians feel weak, open God’s word to strengthen one another (18:18-23)
Paul had already spent a year and a half in Corinth. It’s likely he felt weak as God spoke to him in a vision. He’s strengthened by the word that God speaks to him. Why does he take an unusual route? He points the church to God when they feel weak. He uses God’s word to preach the message of the gospel. The church is built as the word spreads widely (19:20). When we feel weak, let’s open God’s word.
When Christians disagree, explain God’s word more accurately to one another (18:24-28)
Apollos appears faultless. He’s mentioned in 1 Corinthians 1:11-12. He speaks eloquently and is very persuasive. The Corinthian church had started to quarrel. Paul isn’t criticising him. It’s God’s word, not engaging speakers that advance the gospel. One godly Christian couple with a Bible have all they need. Who likes to be corrected? Apollos cares more about the gospel than about his own reputation. As we open God’s word with each other, we are participating in a great activity, as we grow as Christians.
When people are confused, teach God’s word until they are clear (19:1-7)
Paul teaches them until they are clear (19:4). He’s so committed to teaching the Ephesians that he remains with them for two years. As Christians we need to rediscover how to disagree well. It seems that the twelve men aren’t Christians when Paul meets them. On hearing the gospel they receive the Holy Spirit. Why does Luke seem to emphasise the gifts of tongues and prophecy? He wants to reassure his readers that they are Christians. The context of which tongues and prophecy happen needs to be understood in terms of 1 Corinthians 12-13. People may believe different things about prophecy. As we talk to each other, have the Bible open. Let’s listen and meet with the Lord about these things.
It’s God’s word, not our experiences that build churches.
