When I first heard this sermon by W.A. Criswell more than 20 years ago I was wonderfully encouraged. Founders Ministries got permission to distribut hundreds of copies of this message on cassette tapes. Dr. Criswell was a great preacher. He could rightly be designated the "Grandfather of the Conservative Resurgence."
A friend recently alerted me to the fact that this sermon is available on youtube. It is so helpful (not to mention quotable) that I thought it would be great to have all 4 video sections available in one place.
EDIT: I just learned that the transcript for this sermon is available here from the Criswell Sermon Library.
