To evangelize means to tell people the good news about what Jesus did for us. In the book of Acts, everyone did it. Not only the apostles but every Christian did evangelism (Acts 8:4). Passages such as Romans 15:14; Colossians 3:16; 1Thessalonians1:6-10; Hebrews 3:13; 1John 2:20, 27, indicate that every Christian was expected to evangelize, follow up, nurture and teach people the Word. This happened relationally through one person bringing the gospel to another within the context of a relationship.
According to Michael Green, early Christianity grew through the laity, not trained preachers and evangelists. The mission of the church was carried on through informal conversations in homes, shops, on walks and around market stalls, and they did it naturally and enthusiastically (Evangelism in the Early Church by Michael Green).
In the early church, a person’s strongest relationships were within the household, i.e., with blood relatives, servants, clients and friends, so when a person became a Christian, it was in the household that he or she would get the most serious hearing. If the head of the household became a believer, the entire home became a ministry centre in which the gospel was taught to all the household members and neighbours.
The home could be used for systematic teaching and instruction (Acts 5:42), planned presentations of the gospel to friends and neighbours (Acts 10:22), prayer meetings (Acts 12:12), impromptu evangelistic gatherings (Acts 16:32), follow up sessions with enquiries (Acts 18:26), evenings devoted to instruction and prayer (Acts 20:7), and fellowship (Acts 21:7).
As Christians, we need to be like our neighbours in the food we eat and the clothes we wear, our dialect, general appearance, work life, recreational and cultural activities and civic engagement. We should participate fully with our neighbours with regard to excellence. We should be very good at what others want to be good at. We should be skilful, diligent, resourceful and disciplined. It is that similar appearance with the surrounding community that opens up unbelievers to any discussions of faith, because they recognize believers as people who live in and understand their world. It also gives unbelievers a glimpse of what they could look like if they became believers. It would be very good if unbelievers in the business world met Christians in their setting and also if artists met fellow artists who are Christians.
