This book describes such a thing, and talks from both experience and scripture.
From the young age of 19 David pastored his own church in the once gold rich Mt Morgan, Australia. For 14 years David experienced the up and down life of a rural minister in a small town with high unemployment and the ebb and flow of life.
Back when Google was new, David discovered Adwords as a method to promote non profit ideas and started using Google Ads to share the gospel with people linking them to resources and information on his websites. This was a novel idea at the time, the ads were cheap with no competition. In a space of 2 years David introduced 3000 people to Christ and shared the gospel with over 40,000 people in about 20 languages from over 100 countries. Many people joined churches as a result.
