Apostolic Conversion audio?

I have the book "Apostolic Conversion" by Art Katz (very good reading). It says that is is a verbatim transcript from a sermon. Does anybody know where I can find that particular audio sermon?

Yes, you can find it on his website. Here's a link to the catalogue [url=http://www.benisrael.org/catalog/audiotape_catalog.htm]Art Katz website[/url]

If the Lord allows, I would suggest another very powerful sermon entitled "One Thing You Lack." I don't believe Brother Greg has posted it here but it's a very convicting sermon as well.
