That verse says absolutely nothing about a human consciousness being destroyed. Now, you have your whole bible with you, show me anywhere in it that a human consciousness is destroyed forever. Now if its what you believe, you should have at least 3 to 10 verses bearing witness to it; lets have them.
I'm sorry but you are assuming that dead people are conscious. I do not assume that. When the person is destroyed, they do not retain consciousness. If you think that people who are (as the Bible says) "no more" are alive and conscious while they are "no more" then it is up to you to prove that assumption.
I just believe what the Bible says, and when the Bible says that the wicked will be destroyed and will be no more, that's what I accept.
But if you believe that the Bible says that people who have been destroyed and are no more actually are not destroyed and remain alive forever, then post your evidence from the Bible of this. Because honestly, I have never seen even one verse from the Bible that says that people who have been destroyed and are no more will continue to conscious for all eternity.
