If someone wanted to hear the Gospel, they could seek it out outside of their homes.
When will an unregenerate person want to hear the Gospel? Furthermore, when would a unregenerate person seek the Gospel out?
It is agreeable that we should rethink and possibly consider alternate ways of evangelism to avoid imposing, but the aforementioned quote might lead us to laziness. Fundamentally, this "con" is biblically refutable. If we only share the Gospel when someone (unregenerate) wants to hear it, then we might never share it. Also, I think its unbiblical to wait for an unregenerate person to "seek it out outside their homes." Perhaps if they have already been regenerated, this might be a possible conclusion, but otherwise, this con is invalid.
Ben,
I know "street preachers" who have bragged to me about getting on public buses and "trapping people" (their words, not mine) by sitting in the aisle while the "target" of evangelization was next to the window, unable to switch seats, and then preaching to them throughout their bus ride. This seemed coercive, but their rationale was the same as yours...unregenerate people don't willingly listen to the Word, so you must give it to them whether they like it or not.
Another preacher I know is aware of certain townships where the noise ordinances are lax and so he is able legally to blare his amplification system in a way that is bothersome to passers-by and local businesses. Some complain, but legally they cannot do anything and so the street-preacher carries on... In the name of Christ, he is turning people against the gospel everyday by obnoxious activities. His rationale, again, was the same as yours, plus the added rationale of, "I can't truly turn people anymore against the Lord than they already are, since they are already unregenerate..." But I disagree with this.
I believe in the past, people politely sat and listened to evangelists or even the cults, despite having their private space violated. However, now people often lash out at street preachers and those who invade their private space. Sadly, some smug street preachers often then use this response by people as further evidence that, "those people hate the gospel" when, in reality, they are just tired of rude people bothering them.
Whenever it comes to forms of evangelism where we intrude upon another person's property or personal space or break the peace of their silence (i.e., they are sitting alone or listening to an ipod with earbuds on a bus or engrossed in reading a book), I think we ought to rethink our methods to see if they are befitting a servant of the Lord who is to be gentle and speak with grace and serve others.
