What is the book of Enoch? (eNewsletter)
First of all, Enoch is mentioned in Genesis, Luke, and Hebrews; and the book of Enoch was quoted by both Jude and Peter.
It is not included in the Bible we have today, but there's a good reason for that. It was completely unknown prior to the KJV Bible and all of the pre-KJV translations and collections of scripture, so there could be no way for it to have been included in the Bible we have today.
Enoch, like Elijah, was taken to heaven by God without having to die in this life: Gen 5:24 And Enoch walked with God: and he was not; for God took him. - and - Heb 11:5 By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God.
The book of Enoch was first discovered in Africa (Ethiopia) in the mid 1700's and then also found among the Dead Sea Scrolls. Enoch was the great grandfather of Noah. He gave his writings to Methuselah (the son of Enoch and grandfather of Noah), and Noah to preserve them "so they can be delivered to the generations of the world". Is it a book we should study and consider as the word of God just like the other major prophets? I can't answer that question for you, but I have read it, have found no direct contradictions to the Bible in it, find that many places confirm and expand on what we have in the Bible, and find the prophecies fascinating, such as the prophecy of the flood and how it gives us a greater understanding of the world prior to the flood. And, the "10 weeks" prophecy where each "week" is an "era" or period of time (looks like they are about 600-800 years each). Since Enoch is mentioned several times in the Bible, was a man of God, and the book of Enoch was quoted by Jude and Peter, I tend to lean toward it being authentic and inspired by the Spirit like the rest of the Bible.
It goes into great detail about the angels who sinned: Genesis 6:4 and 2 Peter 2:4...
And it gives us an understanding of where evil spirits come from, where magic first came from, etc...
Plus it explains "hell" much more fully. I recently did a study on hell and determined through the Bible that it (Sheol and/or Hades) is "the place of the dead", not just for the wicked but it has several parts including a good part for the righteous dead. In Enoch it gives us even more information!
I recommend giving it a read if you have not already.
