Evangelism appears to follow seven kinds of growth patterns: internal growth, external or numerical growth, biological growth, conversion growth, transfer growth, extension growth, and expansion growth. Among these kinds of growth patterns there are nine types of evangelism: personal evangelism, crusade evangelism, mass (media) evangelism, saturation evangelism, super aggressive evangelism, life-style of evangelism, busing evangelism, front-door, side-door, and Oikos evangelism.
Each type of evangelism has its own merits, while some have more obvious weaknesses than other types. Personal evangelism is the sharing of the gospel by one individual to another. This type of evangelism is needed and should be practiced by those who follow Christ as this was Jesus’ example in his ministry (e.g., Nicodemus, woman at the well). However, personal evangelism was not the only type of evangelism practiced by Jesus. Crusade evangelism is a broader effort intended to reach a wider geography and range of people. Jesus demonstrates this type of evangelism in Mark 1:38 by directing his disciples to go to other nearby villages so that he could preach. Mass (media) evangelism incorporates other media besides the voice of the preacher. This can range from electronic media, such as the Internet or e-mail to visual media, like billboards, signs, mailings, or brochures. Announcements also fall under the umbrella of media evangelism, such as radio, television or in the case of Jesus – other disciples (Luke 9:52). Saturation evangelism is an effort to use all means to reach the unsaved. An example of this is found in Acts 5:28 – a passage that could rightly be titled “Operation: Saturation.” Paul’s intent was to win as many as possible. The question becomes, “What is possible?” If saturation evangelism reveals the possibilities in evangelism, it may then be perceived as a method to utilize in order to know what limits exists. The fifth type of evangelism is called super-aggressive evangelism. Super-aggressive evangelism differs from saturation evangelism in the way the process is gone about. Saturation evangelism uses every mean, while super-aggressive evangelism uses every “ounce” – that is it uses effort versus tact. Life-style of evangelism is a type of evangelism that attempts to lead others to Christ through a process that allows others to see the gospel lived out so that the meaning of the gospel’s message is not lost by proclamation alone. This method of evangelism may be susceptible to a quieting of the voice of the gospel. It raises questions as to how long a person should wait for the “event” to happen that opens the door to the spoken gospel. It clearly has its strengths as even 1 Timothy 4:16 supports; however its weaknesses are also obvious. Busing evangelism was a booming method in the early 70s and was useful for bringing in children and excitement. It was also a facilitator of side-door evangelism. Front-door evangelism or event evangelism incorporated an invitation or event that would have the effect of drawing people to the “front door” of the church. Side-door evangelism incorporates organizations, relationships, service, recreation, Bible study, and life-style evangelism. Oikos evangelism derives its name from “house and household” found 62 times in the New Testament in connection with evangelism. The methodology is centered on reaching groups of people who are socially connected. It is designed to focus on those who are most receptive and is intended to provide adequate time to plant and water.
Although there are choices that may be more appropriate for a general approach to evangelism, not every method will work in every situation or environment. As Jesus used multiple methods of evangelism, including the Oikos type, so we will find different methods working for different situations.
