This is a bit off the trail of the original post, but posting seems to have slowed on that point anyway.
What method do they use when going? We would usually arrange several sessions. It sounds like they were going for a decision for Christ on the first contact?
Was there a particular lead you would use when they first opened the door, or just leave it up the to the Spirit as to where it goes?
Well, we have a particular day out of the week that is our designated "soul-winning" time which is Saturday in the morning. However, there are many who go on Sunday after the church service in the morning until the time when the evening service starts. We target a specific neighborhood that we either haven't been to yet, or one that we haven't been to in a long time and we take a team out there, splitting up people in pairs, men with men and women with women. One of the paired persons is a talker who gives the Gospel, asks the questions, and leads the prayers, and the other is a silent partner who holds the books, CDs, tracts, Bibles, etc. that we give to those who get saved or are willing to accept them. The silent partner position is perfect for those who have never done soul-winning before, so they can get experience and an example of how to do it, as well as having the gratification of participating in giving the opportunities for people to receive salvation.
Also, with each contact, we give people (who are willing to listen and don't slam the doors in our face), the choice to accept or reject the Gospel; we go through all of the points and explain it to them in full, and afterwards ask if they want to believe on the Lord Jesus Christ. Most who are willing to listen and engage seem to lean more towards it, and many who are already saved are able to have their faith reassured, especially those that are out of a church and don't regularly walk in the Spirit.
When we knock on the door, we always invite them to our church and ask them where they go to church if they do go to one (which is the perfect ice-breaker for getting the subject rolling, and also gives an idea as to what they most likely believe regarding the faith); then no matter what they answer, we always ask something to the effect of, "God forbid, if you died today, do you know with certainty that you would go to heaven?" And depending upon their answers, we give them the Gospel by walking through certain key scriptures with them in the Bible if they're willing, which takes no more than usually 10 to 15 minutes. Sometimes, we come across strong men and women in the faith that answer every question and even back up their beliefs with the scriptures we already have selected, which is always a fantastic thing to see, and even sometimes, we come across people who don't even know who Jesus Christ is; or, if they do know the name, they don't know why its significant or what it means.
Our style is probably more on the aggressive side (not as in offensive or mean, but direct and confrontational). What about you guys?
