I did some research and found out that "The Cost of Declaring His Glory" was delivered by Helen Roseveare (not Mrs. Wurmbrand). The hole sermon is writen on this site:http://www.urbana.org/_articles.cfm?RecordId=572It is, indeed, very powerful !!!
OK thank you I will fix this, this is in reference to:http://www.sermonindex.net/modules/newbb/viewtopic.php?topic_id=8249&forum=16&4
