Ya i watched these Vids last year.. i was very impressed because Mark Fairley seems quite young for the breath of knowledge and insight contained in his video series 'Know Thy Enemy'..
After doing some more research in similar teaching styles i came across Walter Veiths series; 'Total Onslaught'( Link at the bottom ).. After watching some of it I knew that it was not only similar but almost word for word in some instances.. It is a very long and intensive teaching series, containing 36 videos that are around 1.5 hours in length!!

Walter Veith is a professor and a great speaker.. he delivers his teaching very fluently.. I am 99.5% sure that Mark Fairley took and condensed Veiths longer and more intensive video series and made them a little easier to digest for the average attention span.

BTW, Veith is a Seveth Day Adventist teacher, so be careful not to fall into any religious affiliation if you get into these.. you may be tempted to..

Stay free my friends!
