A warning to sinners (Revelation 21:8)

It says that the cowards, the unbelievers (atheists), the abominable, the murderers, the sexual perverts, the sorcerers, idolaters, and liars will be in the lake of fire. As of now Hell is NOT the lake of fire. Hell is a place where unrepented sinners go to be tortured. Hell will become one with the lake at the end. But what I am getting at is the unbelievers part. As a former atheist, I didn't care one way or another about God, or about heaven or hell. I though when I die, it will be it. My family is Christian. And when I read Revelation 21:8, it was a wake up call. It was the night when I became a Christian (September 4, 2009) and I thought that if I would have died a day before, I would be in hell then the lake of fire. The lake of fire is the second and forever death. I am glad that police officer showed me my mistakes of atheism before it was too late.
