Let us observe the Scriptures which show that the dead are not conscious.
[63]"In death there is no remembrance of thee: in the grave who shall give thee thanks ?" (Psalm 6:5) Thus is shown that they have no memory while dead.

"The dead praise not the Lord, neither any that go down into silence." (Psalm 115:17) Hence they could not speak while dead.
[64]The dead cannot breathe, think, or feel.

"Thou takest away their breath, they die, and return to their dust." (Psalm 104:29) "His breath goeth forth, he returneth to his earth; in that very day his thoughts perish." (Psalm 146:4) A person when unconscious does not feel.

This is illustrated by the fact that when a person is taken to a hospital for an operation the surgeon puts the patient under an anesthetic, puts him to sleep so that he cannot feel during the operation.
[65]Again the Scriptures read: "The living know that they shall die, but the dead know not anything.

Also their love, and their hatred, and their envy, is now perished." (Ecclesiastes 9:5,6) Being unconscious, they know not anything when dead.
