The biggest threat?

When asked that question in a chat hosted by the Washington Post, here's what Mike Horton had to say:

Norfolk, Va.: What do you consider to be the greatest threat to Orthodox (biblical) Christianity today?

Rev. Dr. Michael S. Horton: Shallowness. It is far worse than heresy. At least heretics take the gospel seriously enough to distort and deny it. And heresy always makes the church think more deeply about what it believes and why it believes it. However, shallowness is deadly for the Christian Faith.
