There are however disagreements of whether we should even be evangelizing or not. These range from the Great Commission as not even being spoken by Jesus and our Christian example should be enough, to evangelism not bringing others to Christ because of all the poor evangelists in the past. There is, I think valid reasons for thinking that way and it is certainly our responsibility to reach the poor by our example and in many cases as being sufficient. The confusion as to what evangelism is, is that it should be bringing others the good news of a spiritual kingdom, not just the precepts of a religion. The kingdom is to be preached to the poor but that is my point, the gospel needs to be preached as well as lived out, not only in the witness of Jesus but in the power of His name and according to His word.
Evangelism has been misused in the past, there is no dispute on that score.
There have been those that have brought false doctrine and denominationalism and unscriptural dogma in the past as money grubbing, authoritarian purveyors of crass nationalism and exploitation. But we are to do a new thing here and not be bogged down by the mistakes of the past. We are to put away those things and press on to the higher calling. This means that there are some of us who should be planting and some of us who should be watering and some who should praying for the Lord to work in all of us for Him to bring in the increase and harvest. We are His body, living out His life.
