Dumb- simply dumb. Do you not know the scriptures? Ecclessiastes tells us that that All people, righteous and evil alike share a common fate - bodily death. It further states that after death they have nothing more to do with anything that occurs here - nothing.
Ecclesiastes 9:2 All [things come] alike to all: [there is] one event to the righteous, and to the wicked; to the good and to the clean, and to the unclean; to him that sacrificeth, and to him that sacrificeth not: as [is] the good, so [is] the sinner; [and] he that sweareth, as [he] that feareth an oath.
[3] This [is] an evil among all [things] that are done under the sun, that [there is] one event unto all: yea, also the heart of the sons of men is full of evil, and madness [is] in their heart while they live, and after that [they go] to the dead. [4] For to him that is joined to all the living there is hope: for a living dog is better than a dead lion. [5] For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten. [6] Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any [thing] that is done under the sun.
To bottom line this - it means that not only can they not hear your prayers, they are incapable of acting on them. This completely invalidates your assertions. And I would add that attempting to contact the dead in request for intervention is in fact part of necromancy and does so qualify as necromancy. You should learn about what you're discussing before making such statements. And I do mean beyond looking at a dictionary entry or a Catholic talking point.
Believers who die do not go to Abraham's bosoms, but rather go to live with God in Heaven.
I would think you knew this.
