My church in the UK has been doing door-to-door evangelism for about six months.
We have covered most of the area around the church now.
The fruit we have had from this is the grand total of one lady who has become a very regular attender.
Before we visit a street, we put a card through the door to say we're coming, in order to distinguish ourselves from the J.W.s
We've had some good conversations and some folk have promised to come to the church, but only the one lady has come to date.
We have had a small amount of abuse, but that's OK.
God brings the converts all we need to do is obey and evangelize and let Him bring the results. The fruit is the gladness and joy of preaching the word and trusting in treasures to be given in Heaven.
