Why are Christians moving away from the faith?

Recently, some Christian public figures have renounced their faith. In light of this, apologetics specialist Rick Mattson and pastor Jonna Fantz talk about why people are drifting from the faith and how to reach these people. Rick wrote two books that address this: "[amazon text=Faith Is Like Skydiving&asin=0830844112]" and "[amazon text=Faith Unexpected&asin=0692048995]."
