Hi all,
Good discussion. I thought I'd jump in with a short post. A couple people have made comments about what is effective and what "works" in evangelism, and I think what they mean is whether the evangelism succeeds or not. It is impossible to know, however, whether success has been attained without first clearly identifying one's goal. To use an analogy from our school days: We knew we successfully passed a test when our grade exceeded a certain percentage. Had we not known what that benchmark number was, we would have always wondered whether we passed the test or not. Similarly, we need to define clearly what our goals in evangelism are.
If the goal is an increase in the numbers of church attenders, for example, and the church is not increasing in numerical size, then one can say that one's method was not successful. If one's goal is to see souls make an outward profession of faith, and not a single person makes such a profession, then one can say, again, that the method was ineffective. If, however, one's goal is to be faithful and obedient in proclaiming the good news, to teach the word of Christ thoroughly and accurately and to glorify God, then one's ministry will certainly be successful as long as the gospel is proclaimed fully and correctly.
The only criterion, then, for determining success or failure is the content of one's message, not its results. in my opinion, a ministry needs to be evaluated on the basis of its doctrine, not its fruit. If evangelism is defined as proclaiming the gospel of Jesus Christ thoroughly and correctly--and if this is done--then that evangelism has a 0% failure rate.
