Am I reading my diss-meter correctly here? 'Cause I could swear I'm being blown off!

In the midst of a Sunday school series on what it means to be Reformed, we've covered evangelism the past two weeks.

The following are 7 books I would highly recommend on evangelism:

• D. A. Carson (general editor), Telling the Truth
• Walter Chantry, Today's Gospel: Authentic or Synthetic?
• Mark Dever, The Gospel and Persona Evangelism
• Will Metzger, Tell the Truth: The Whole Gospel to the Whole Person by Whole People
• J. I. Packer, Evangelism & the Sovereignty of God
• John Piper, Let the Nations Be Glad!
• Charles Spurgeon, The Soul Winner

Any others you'd suggest?

[Update: Thanks for the other suggestions in the comments.]
