Evangelism is the work of a Christian evangelist, of which all true Christians are obligated to partake to some extent, which seeks to persuade other people to become Christian, especially by sharing the basics of the Gospel, but also the deeper message of biblical truths. Today the Gospel is almost an unknown, so what does the Christian evangelist do? Preevangelism is laying a foundation for those who have no knowledge of the Gospel, giving them background information, so that they are able to grasp what they are hearing. The Christian evangelist is preparing their mind and heart so that they will be receptive to the biblical truths. In many ways, this is known as apologetics. Christian apologetics [Greek: apologia, “verbal defense, speech in defense”] is a field of Christian theology which endeavors to offer a reasonable and sensible basis for the Christian faith, defending the faith against objections. It is reasoning from the Scriptures, explaining and proving, as one instructs in sound doctrine, many times having to overturn false reasoning before he can plant the seeds of truth. It can also be earnestly contending for the faith and saving one from losing their faith, as they have begun to doubt. Moreover, it can involve rebuking those who contradict the truth. It is being prepared to make a defense to anyone who asks the Christian evangelist for a reason for the hope that is in him or her. – Jude 1.3, 21-23; 1 Pet 3.15; Acts 17:2-3; Titus 1:9. What do we mean by obligated and what we mean by evangelism are at the heart of the matter and are indeed related to each other. EVANGELISM: An evangelist is a proclaimer of the gospel or good news, as well as all biblical truths. There are levels of evangelism, which is pictured in first-century Christianity. All Christians evangelized in the first century, but a select few fit the role of a full-time evangelist (Ephesians 4:8, 11-12), like Philip and Timothy. Both Philip and Timothy are specifically mentioned as evangelizers. (Ac 21:8; 2 Tim. 4:5) Philip was a full-time evangelist after Pentecost, who was sent to the city of Samaria, having great success. An angel even directed Philip to an Ethiopian Eunuch, to share the good news about Christ with him. Because of the Eunuch’s already having knowledge of God by way of the Old Testament, Philip was able to help him understand that the Hebrew Scriptures pointed to Christ as the long awaited Messiah. In the end, Philip baptized the Eunuch. Thereafter, the Spirit again sent Philip on a mission, this time to Azotus and all the cities on the way to Caesarea. (Ac 8:5, 12, 14, 26-40) Paul evangelized in many lands, setting up one congregation after another. (2 Cor. 10:13-16) Timothy was an evangelizer or missionary, and Paul placed distinct importance on evangelizing when he gave his parting encouragement to Timothy. – 2 Timothy 4:5; 1 Timothy 1:3. The office of apostle and evangelist seem to overlap in some areas, but could be distinguished in that apostles traveled and set up congregations, which took evangelizing skills, but also developed the congregations after they were established. The evangelists were more of a missionary, being stationed in certain areas to grow and develop congregations. In addition, if we look at all of the apostles and the evangelists, plus Paul's more than one hundred traveling companions, it seems very unlikely that they could have had Christianity at over one million by the 125 C.E. This was accomplished because all Christians were obligated to carry out some level of evangelism. OBLIGATED: In the broadest sense of the term for evangelizer, all Christians are obligated to play some role as an evangelist. • Basic Evangelism is planting seeds of truth and watering any seeds that have been planted. [In the basic sense of this word (euaggelistes), this would involve all Christians.] In some cases, it may be that one Christian planted the seed, which were initially rejected, so he was left in a good way because the planter did not try to force the truth down his throat. However, later he faces something in life that moves him to reconsider those seeds, and another Christian waters what had already been planted by the first Christian. This evangelism can be carried out in all of the methods that are available: informal, house-to-house, street, phone, internet, and the like. What amount of time is invested in the evangelism work is up to each Christian to decide for themselves. • Making Disciples is having any role in the process of getting an unbeliever from his unbelief state to the point of accepting Christ as his Savior and being baptized. Once the unbeliever has become a believer, he is still developed until he has become strong. Any Christian could potentially carry this one person through all of the developmental stages. On the other hand, it may be that several have some part. It is like a person that specializes in a certain aspect of a job, but all are aware of the other aspects, in case they are called on to carry out that phase. Again, each Christian must decide for themselves what role they are to have, and how much of a role, but should be prepared to fill any role if needed. • Part-Time or Full-Time Evangelist is one who sees this as their calling and chooses to be very involved as an evangelist in their local church and community. They may work part-time to supplement their work as an evangelist. They may be married with children, but they realize their gift is in the field of evangelism. If it were the wife, the husband would work toward supporting her work as an evangelist and vice-versa. If it were a single person, he or she would supplement their work by being employed part-time, but also the church would help as well. This person is well trained in every aspect of bringing one to Christ. • Congregation Evangelists should be very involved in evangelizing their communities and helping the church members play their role at the basic levels of evangelism. There is nothing to say that one church could not have many within, who take on part-time or full-time evangelism within the congregation, which would and should be cultivated.
