Andrew Sach, writer and pastor of Grace Church, Greenwich in London, discusses his book 'Are You 100% Sure You Want to Be An Agnostic?' with Glenn Scrivener. They explore the use of comedy in making Christianity fun and approachable. They also challenge the comfortably agnostic to accept Jesus' offer and delve into the concept of the 'agnostic diagnostic'. The hosts share personal stories and discuss having conversations with agnostics. Finally, they wrap up with thoughts on agnosticism, personal evangelism, and book recommendations.
