There is much Bible evidence to demonstrate that the soul is entirely conscious in the after-death state. One of the biblical contexts which sheds light on this subject is Revelation 6:9-11. Read this narrative very carefully
“And when he opened the fifth seal, I saw underneath the altar the souls of them that had been slain for the word of God, and for the testimony which they held: and they cried with a great voice, saying, How long, O Master, the holy and true, dost thou not judge and avenge our blood on them that dwell on the earth? And there was given them to each one a white robe; and it was said unto them, that they should rest yet for a little time, until their fellow-servants also and their brethren, who should be killed even as they were, should have fulfilled their course.”
Note the following facts:
John sees the “souls” of those killed for the cause of Christ under the altar of God. These persons are martyrs, hence their slain bodies
-which have been buried, burned, fed to animals, thrown into the sea, etc. - remain upon the earth. And yet they, as souls, are existing in the presence of God. There is a soul that exists independent of the human body!
Regarding these souls, scripture and logic indicate:
(1) They are vocal — they cry out to God.
(2) They are intellectually curious — they desire to know how long persecution will continue.
(3) These souls have memory — they recall earth’s bloody circumstances.
(4) They are morally sensitive — they believe that the wicked who persecute God’s righteous cause on earth should be punished.
(5) They are capable of receiving blessings —each is given a white robe.
(6) They are able to comprehend admonition — they are told to be patient and rest until the divine plan is fulfilled.
This context is a death blow to the doctrine of materialism, and its kindred dogma of soul-sleeping.
Make notes in the margin of your Bible reflecting these observations.
