The Bible speaks of a race of giants who roamed the Earth before the great flood of Noah's day. Some Bible versions call them “giants”(Darby Translation, Douay-Rheims, King James Version, The Message, etc.) while others call them “Nephilim”(American Standard Version, World English Bible, Holman Christian Standard Bible, New American Standard Bible, etc.). According to Strong's Hebrew Lexicon, the word “Nephilim is defined as follows:
The Bible tells of these Nephilim, revealing that these were the offspring of angels, essentially becoming demigods to the Earth's population during the time of Noah:
Note how this states these giants existed in those days (the days of Noah) " and after that". It is important to note this bit because many believe that the deluge of Noah's day completely destroyed these angel/human hybrids, whereas this Scripture shows that these “sons of God” continued to mate with women after Noah's day (though apparently not on the same scale). This is supported in other Bible books which contain accounts that happened many generations after the deluge:
The Emim lived therein before, a people great, and many, and tall, as the Anakim: (11) these also are accounted Rephaim, as the Anakim*; but the Moabites call them Emim.
The idea of angels having sexual relationships with humankind is a crime in God's eyes, as it fits in the crime of going after “strange flesh”:
(6) Angels who didn’t keep their first domain, but deserted their own dwelling place, he has kept in everlasting bonds under darkness for the judgment of the great day. (7) Even as Sodom and Gomorrah, and the cities around them, having, in the same way as these, given themselves over to sexual immorality and gone after strange flesh*, are set forth as an example, suffering the punishment of eternal fire.
PARALLELS TO MYTHOLOGY
The results of these flesh-and-angel unions created a hybrid between the spiritual realm and the physical realm. Such unusual progeny would be larger and have abilities and power unlike any normal human being due to the angelic traits being passed onto the offspring. It is thought that this supernatural race of offspring originated the lore of gods from ancient mythology. Consider the following:
In ancient Greek and Roman mythology gods came down from the heavens to mate with women, who in turn gave birth to supernatural hybrid humans who possessed amazing abilities and/or powers. This gave rise to legends such as Hercules, Achilles, and the twin boys Romulus and Remus, among others.
Interestingly, these mythologies also have the common idea of a “king” of the gods: Zeus was the king of the Greek gods and Jupiter was the king of the Roman gods. Many who study this lore believe that these different versions of the “king of the gods” all relate to Satan: Since these god-kings rule over the other gods, and since Satan is seen as the ruler of the demons (angels who've sinned), this parallel is drawn.
It is also interesting to note that Satan desired to become a god (Isaiah 14:12-20). Through the guise of being the king of all other gods he would have been able to make his desire come true to a large extent. This ruse would easily lead innumerable people away from the worship of the True God as they, instead, installed him and his fallen angels as gods to be worshiped. This is the way in which these fallen angels have forged the pantheons of gods: Greek gods, Roman gods, Norse gods, Hindu gods, Wiccans gods, Shinto gods, and all other groups who have honoured multiple gods. And when we celebrate Valentine's day by using the Roman god Cupid we are actually honouring a demon (This is why many Christians avoid Cupid decorations on Valentine's day). And when we speak the name of the holiday of “Easter” we are speaking the name of the goddess Eastre, honouring yet another demon (This is why many Churches prefer to use the title “Resurrection Sunday” instead).
This is exactly why the Bible states that acts of idolatry are, in truth, the worship of demons:
...And the Bible also forewarns that in latter times people will be deceived into following the doctrines of demons (a.k.a. Devils):
We can see the influence of such demonic teachings today, as many religious groups enforce celibacy or require abstinence from meat, teach doctrine that is not in the Bible, and frequently behave in very hypocritical ways.
Suffice it to say, Satan and his fallen angels have done a successful job in insinuating themselves as gods in our world. Beginning with the Nephilim, things have progressed to the point to where we now have an array of Greek, Roman, Norse, Hindu, Wiccan, Shinto and tribal gods who are worshiped throughout the world. These pagan gods are honoured in almost every facet of our lives: In the names of the months ("January"), the names of the days of the week ("Thursday"), in holiday symbols ("Cupid"), and the names of the planets in our solar system ("Jupiter"). We have a chocolate candy company named after the god of war ("Mars"). We name our children after the goddess of beauty ("Venus Williams"). We name our space missions after gods ("Apollo"). A book of maps is named for a god ("Atlas"). We name our automobile companies after gods ("Saturn"). We name our web companies after gods ("Juno"). We name our sports companies after gods ("Nike"). Yeah, I could go on and on – Clearly, Satan has saturated our world with his demonic gods so thoroughly that we don't even blink when any of the above-mentioned things are mentioned.
This is something that won't be taken lightly when Jesus Christ returns to gather His true worshippers.
