Death: The Second Death
Bible study on death.

Rev. 2:10-11

There are two deaths, physical and spiritual.

We should not fear physical death but spiritual death (Matt. 10:28). Perfect love casts out fear (1 Jn. 4:18).

Rev. 20:6

Someone who has part in the first resurrection will not be harmed by the second death.

Rev. 20:14-15; 21:8

The second death is being cast into the lake of fire.

Everyone whose name is not written in the Book of Life is cast into the lake of fire. Christians' names are written in the Book of Life (cf. Phil. 4:3). If a Christian returns to a life of sin, his name is blotted out of the Book of Life (Rev. 3:3-5).
