Is evangelism an individual sport or a team sport? It’s both. Jesus commands every Christian to make disciples. But we should make disciples in and through our churches.
Think of the first chapters of Acts, where the apostles proclaimed the resurrection. Behind them was the church, living together and sharing everything in common, ‘praising God and enjoying the favour of the people’ (Acts 2:47; also 5:13). Somehow, the life of the church served as a positive witness to the gospel. Then, when persecution broke out and the church scattered, ‘Those who had been scattered preached the gospel wherever they went’ (Acts 8:4).
So the leaders evangelised. The members evangelised. And their life together commended the message.
