They are just saying people to need to spread the gospel. They are just sharing ways of doing so. Ways which happen to be of the Master (Jesus Christ)
Could you provide me with a Bible passage that shows Jesus using this type of confrontational approach?
The closest I was able to come up with is Mark 10, where Jesus is talking with a citizen.
18"Why do you call me good?" Jesus answered. "No one is goodexcept God alone. 19You know the commandments: 'Do not murder, do not commit adultery, do not steal, do not give false testimony, do not defraud, honor your father and mother.'[d]"
20"Teacher," he declared, "all these I have kept since I was a boy."
At this point, did Jesus ask the man:
"Have you ever lied?"
"Have you ever stolen anything?"
"Have you ever lusted after a woman and committed adultery?"
and then, after the person admits, often with some coaching that, yes, he probably has, follows that with
"Doesn't that make you a lying, thieving, adulterer?"
So, instead
21Jesus looked at him and loved him.
Jesus then asked him to do something that Way of the Master probably won't ask you to do:
"One thing you lack," he said. "Go, sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me."
The passage ends with this question from the disciples:
26The disciples were even more amazed, and said to each other, "Who then can be saved?"
And Jesus answered:
27Jesus looked at them and said, "With man this is impossible, but not with God; all things are possible with God."
As Christians, I think we have an obligation to be as effective as possible in bringing as many people as possible to an understanding of the Lord, and in helping them to become committed Christians that will become part of a body of believers (a Church!), and be baptized. I personally am wary of any ministry that doesn't make these goals their fundamental objective- like, how else is the church going to grow and flourish?
I believe Christian organizations that have theologically-trained and ordained ministers, subscribe to the type of independent ethical and financial standards adopted by institutions like the ECFA (Evangelical Council For Financial Accountability), and clearly follow the Bible and subscribe to the teachings of the Gospel are more likely to be credible and successful than those that don't follow these standards.
I personally am wary of ministries that doesn't follow these standards, while at the same time being critical of long-established Christian organizations that do. Should we as Christians be concerned about these matters- I think we have to be if we are to ensure that what we do is effective and does not, like some of the ministries that we have seen over the years, hurt the Christian faith, and turn people away from ever considering Jesus as their personal savior and Lord.
Is this ministery more effective than others? In my opinion, no; I think a more gentle, considerate approach is necessary- but absolutely one that follows the Gospel and emphasizes the need for unbelievers to repent and follow Jesus if they wish to be with Him in Paradise.
Could this ministry be effective? I guess time will tell, and I will remain open minded and willing to change. Effective ministries flourish, those that aren't whither away and die.
I think I have now presented my opinions on this issue in an honest and forthright manner. Unless there are new points that need to be addressed, I don't intend to follow it any further.
