The Book of Revelation in the following verses indicates otherwise:
the twenty-four elders fell down before the Lamb, each holding a harp,
and with golden bowls full of incense, which are the prayers of the saints
(5:8).
I saw under the altar the souls of those who had been slain for the word of
God and for the witness they had borne; they cried out with a loud voice,
O Sovereign Lord, holy and true, how long before thou wilt judge and
avenge our blood on those who dwell upon the earth? (6:9).
And the twenty-four elders who sit on their thrones before God fell on
their faces and worshiped God, saying, We give thanks to thee, Lord God
Almighty, who art and who wast, that thou hast taken thy great power and
begun to reign. The nations raged, but thy wrath came, and the time for the
dead to be judged, for rewarding thy servants, the prophets and saints, and
those who fear thy name, both small and great, and for destroying the
destroyers of the earth (11:16-18).
Sixth objection: But isnt speaking to the dead forbidden in the Old
Testament?
The relevant passage in the Old Testament is Deuteronomy 18:10-12:
There shall not be found among you any one who burns his son or his
daughter as an offering, any one who practices divination, a soothsayer, or
an augur, or a sorcerer, or a charmer, or a medium, or a wizard, or a
necromancer. For whoever does these things is an abomination to the Lord;
and because of these abominable practices the Lord your God is driving
them out before you.
