Today is the first International Day for the Unreached. See the official website here. See the live event here. Beyond has put together a resource page here, which includes a pair of new videos (I think this one is really powerful), links to articles and books that may be useful.
Kent Parks (CEO, Beyond) and I were on Point of Network to talk about the day - you can watch our interview here (now in full video!)
For more information about the unreached, you can search this website for the phrase. I use it a lot.
Eric D on the Traveling Team talks about the "hijacking" of unreached: how it's used for lots of things it's not intended for
Globalcast Video: Pastor Chris Lazo talks about the opportunity and what the church should do about it

Here are two Bible.com reading plans on missions/unreached:
Are we getting anywhere in mission? https://missionexus.org/are-we-getting-anywhere-in-mission/
God’s Big Heart for the Least: https://missionexus.org/gods-big-heart-for-the-least/
Great Commission quotes: https://missionexus.org/great-quotes-on-the-great-commission/
Perhaps the key thing to do on this day is to join with other believers in prayer, but also to use this day to make people at our church aware of the day - so that next year, an even greater participation can happen.
And, we can build networks of people working on this. In fact, this blog post is in large part the beneficiary of such a network: many of the links were recommended to me by my friend Jon Hirst. He is a Generous Mind.
