Sam Chan is a genius! He's managed to publish three books while only using the material for one!
Seriously though, over the last couple of years, Sam came out with "Evangelism in a skeptical world", which was well received, but some thought it a little too unapproachable for a general audience. Next came "How to talk about Jesus (without being "that guy"). It was aimed at general audience & contained a lot of the material in Sam's former book, just explained more simply.
"How do we talk with Skeptics" is simpler still, boiling down Sam's earlier thoughts into ten simple ideas. If you knew someone who wanted to think a little more about how they engage with other people, this is a short and simple thought starter, able to be read in a couple of hours!
