Art,Your interest in the Nephilim is very timely and important. The mingling of the physical seed of Satan and men is now a possibility via DNA modification and a thorough explanation is now available in book form that any lay person can easily understand.I recently read the book "Corrupting the Image - Angels, Aliens, and the Antichrist Revealed" (2011) by Douglas Hamp (www.douglashamp.com). I recommend this book if you want to be brought up to date concerning the Nephilim, their history and how they will play a role in the last days.The blurb on the back of the book says:Her seed brought forth the Savior - Satan's seed will bring forth the DestroyerThe prophecy of Genesis 3:15 states the Serpent will one day mix his seed with humanity as a counterfeit of the Messiah. Jesus told us that the last days will be like the days of Noah when fallen angels mixed their seed with humanity.In the book of Daniel we read that they will again mingle with the seed of men. That day of fulfillment is now!"Riveting! This book brings together, perhaps for the first time ever, a comprehensive explanation of how the Antichrist will be a genetic counterfeit of the virgin birth. This book is at the cutting edge of research and is written so that the average person can grasp the sinister plan that is unfolding before our very eyes!" Dr. Kenton Beshore, President of World Bible Society"One of the most important books of our time! It will help you understand Satan's goal to alter the DNA of mankind so that a false government leader plus a false religious leader can be produced to join Satan as an unholy trinity. The Bible is the Word of God, and Doug's book is based on the Bible. We need to understand these major truths that are already beginning to impact life on earth." Don Secrist, Founder www.bibleeasylearn.org"Startling! This book takes what the Bible says and magnifies it so you can see clearly how genetics is vital to opening the door for the return of the Nephilim. No matter where you stand on biblical eschatology, this book will affect you. Read it." Dr. J. David Lehman, Bible Researcher and Lecturer.Douglas Hamp earned his MA in the Hebrew Bible and the Nacient Near East from Hebrew University of Jerusalem, Israel.The book is paperback and can be found at Amazon,com and other book sites.YBIC,Robert
