The following is a quote taken from Mack Stiles' new book,
Marks of the Messenger: Knowing, Living and Speaking the Gospel. I am almost through with the book, and I have thoroughly enjoyed it. I have found it both helpful and valuable. This book could be used by an individual as well as a group - all of which would be informed, equipped, and encouraged to be better evangelists.
"The ultimate mark of conversion, as I've heard Mark Dever rightly say, is not walking an aisle, but picking up a cross."
Justin Taylor has several endorsements of the book posted on his blog
