A couple months ago, my twin brother Mark (and his family) got to meet Joshua Harris' brothers, Alex and Brett. They were in Japan for a conference to give some very important messages for young people and for those who raise them. All of the Harris' were (or are) being home-schooled. In fact, their dad, Gregg, is one of the leaders of the home-schooling movement in the USA.
Mark told me that he was very impressed with these guys and their humble, God-centeredness. In addition, it's clear that they are intentionally seeking to engage the culture for Christ. They are challenging young people to Do Hard Things and they are living this out in many ways including their active involvement in politics. What a great example of homeschooled kids growing up with a heart for Christ and a heart for the world they live in!
