I have been studying the Book of Enoch. The Holy Spirit has helped me to understand many similarities in the Book of Enoch and the Book of Revelations composed by the Apostle John on the Isle of Patmos. During the past years with my Mama, we studied the Book of Revelations multiple times. When I downloaded the Book of Enoch and we began to study his writing, we saw many similar phrases and descriptions of the visions of Heaven shared by Enoch and John.
I do not know why God's Holy Spirit has revealed these mystical visions to me - but I am grateful to be aware of these miraculous visions from God. I saw this video and it confirms so many impressions that my Mama and I shared about these two amazing volumes written by men many years apart. Thus confirming the Book of Revelations as a final chapter of God's great judgement and His amazing mercy and grace to humankind.
