Christians should “door-knock” in order to spread the Gospel.
A Christian friend of mine who had come from overseas spoke at our bible study here in Idaho. This person told the class that when they had moved to England for some undergraduate work, a neighbor told them, “Do not bring your religion into my home.” They honored the man's request. During the next two years, however, they became friends with their neighbor. It was at that time he he then asked, “Can you please tell us about your Christian God?” The man and his family were eventually converted to Christ.
Most Christians believe that they need to get out in the streets and pound the pavement and rattle doors to spread the Good News. It's a noble idea but mostly ineffective. Why? Here's my short list:
If you want
to convert someone to Christ, first take time get to know them. Show
some concern for them. A card at Christmas, a few conversations about
who you are and who they are. You get the idea. The last thing they
want is for a stranger to interrupt them while they're putting
groceries in the car. In my 60-odd years, I've never known anyone to
be converted by a door-knocker. Does that mean it never happens?
Could be, but I've never known anyone who came to Christ because of a
stranger's appeal to the faith. Not unless they were in dire straits
due to addiction, imprisonment, etc. Again, I'm not saying it never
happens, but they are the exception.
I've heard some say, “I preached the gospel to them; if they go to hell, it's their fault.” Such an attitude demonstrates a lack of real love for the lost. At times, even Jesus fed the thousands—cared for them—before preaching. At the same time, those living in the times of Christ were universally hungry for the Gospel. In our overfed, overweight, and amoral American culture, you have to befriend folks to be an effective evangelist.
And that, my friend can be a long, long effort.
