This is probably my fourth draft of this post. Initially, I thought about commenting on some of the faults found in many church growth strategies, but felt that I was simply attacking a straw man. So, I will stick to the book of Acts.
As I have been reading Acts, I have noticed some themes thus far. One theme has been the power of the Holy Spirit. The Apostles accomplished much for Christ and his church because they relied on his Spirit to empower them to share the gospel. As a result, the church grew.
Another theme, which I want to quickly write about today is preaching. Not only did the church grow through the power of the Holy Spirit, but that growth was accompanied by preaching the gospel (Romans 10:17). And not only preaching once a week, but preaching and teaching as the disciples traveled throughout the region. Such active preaching in seen in Acts 8, where the disciples continue to preach, even in the midst of extreme persecution.
Now those who were scattered went about preaching the word. Philip went down to the city of Samaria and proclaimed to them the Christ. (Acts 8:4-5 ESV)
But when they believed Philip as he preached good news about the kingdom of God and the name of Jesus Christ, they were baptized, both men and women. (Acts 8:12 ESV)
Then Philip opened his mouth, and beginning with this Scripture he told him the good news about Jesus. (Acts 8:35 ESV)
But Philip found himself at Azotus, and as he passed through he preached the gospel to all the towns until he came to Caesarea. (Acts 8:40 ESV)
