But do not think that this is the only reference to this truth found in the Bible, there are others.
Of course. But we were speaking of Gen. 6.
The other sources are even more 'limited'. They don't even use the word Nephilim. Is this not true as well ?
You are making the same mistake that the 3 blind men did when they each felt of the elephant and described it differently. They each "saw" just a tiny part of the whole and though that was all there was.
You have to read all of the Bible, study it verse by verse, precept by precept, and most importantly ask God to give you understanding. Satan has done a very remarkable job hiding this from us, he does not want us to know that he tried to infiltrate earth with the offspring of his fellow fallen angels, that he almost accomplished his goal and would have, but God destroyed them all in the flood and began the earth again with Noah's family. Matthew 24:37 says: "As it was in the days of Noah, so it will be at the coming of the Son of Man." The scripture is telling us that in those days just preceding Christ's second coming, it will be as in the days of Noah, Nephilim (fallen angel's offspring once again attempting to dominate and many many people obeying and following their evil degenerate nature).
Matthew 24:37 does not mention the word Nephilim, yet we know what "in the days of Noah" means if we study the scriptures about Noah and the flood..... verse by verse, precept upon precept (by the way, God teaches us the "precept upon precept" lesson in Isaiah 28:10)
This whole Nephilim topic has been shoved to the back of the burner by our pastors for a long time. They admittedly know the truth, but they hesitate to teach on it for some reason. Perhaps they have been led by God to do so. But more and more of them are seeing that the time is fast approaching that we need to understand this topic. That is why I linked a good video that is well done and based on Bible Scripture and will be a good introduction for you, then you can delve into the Scriptures your self and confirm.
