Enoch - And when the Righteous One shall appear before the eyes of the righteous, Whose elect works hang upon the Lord of Spirits, And light shall appear to the righteous and the elect who dwell on the earth, Where then will be the dwelling of the sinners, And where the resting-place of those who have denied the Lord of Spirits? It had been good for them if they had not been born.

Notes

The book of Enoch is not part of the canonical scriptures (The Bible) we know today and we don't know how accurate it is.

Some belive while Enoch is not inspired by God that it still serves as a historical book on the time before the flood. It's also quoted in the New Testament in Jude 1:14-15.

Because of this I wanted to include this book for historical reasons.

I would recommend reading the Bible first and foremost as it should be your foundation. Then if you are intrested you can take a look at the book of Enoch.
