One can see that the Bible has numerous reference and statements showing that this is not true. That fellow who's sleeping on the couch knows nothing while he's asleep, and if death is a sleep, then he knows nothing after his death. In death a man's brain is dead, his mind is dead, he feels nothing, he knows nothing, and he is nothing. This is nothing new. Look what Martin Luther and several other well-known Christians have said about the sleep of man in death.
Truth is no, and never has been, established by human majorities.
Theological truth is only based upon the immutable Word of God, and determined by its inspired precepts and principles.
