Wanted to shout out a recent podcast episode from @Cmarquis and Nathan. They highlighted some pretty major statistics:

61% of Christians have never shared their faith

42% of the world still live in unreached people groups

There are 900 churches and 78,000 evangelical Christians for every one unreached people group

51% of church attendees in the US were unfamiliar with the term 'Great Commission'

Here's the podcast if you want to give it a listen: https://forgeforward.org/blog/2021/07/13/episode-84-fresh-god-stories-from-the-field/
