The Bible contains many records revealing information on the abyss, the devil, and death.
This book provides God's viewpoint regarding the abyss and the spirits confined in the abyss; the devil's motives and activities; how death came to pass for mankind; and the truth that Christ Jesus defeated the devil.
The Lord Jesus Christ now has the keys of death and gravedom, and at a future time all against God and the Lord Jesus Christ will be completely destroyed in the second death.
