“And round about the throne were four and twenty seats: and upon the seats I saw four and twenty elders sitting, clothed in white raiment; and they had on their heads crowns of gold. . . . The four and twenty elders fall down before him that sat on the throne, and worship him that liveth for ever and ever, and cast their crowns before the throne, saying, Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created” (Revelation 4:4, 10-1).
“And when he had taken the book, the four beasts and four and twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the prayers of saints. . . . And the four beasts said, Amen. And the four and twenty elders fell down and worshipped him that liveth for ever and ever” (Revelation 5:8, 14).
“And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God, Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned” (Revelation 11:16-7).
“And the four and twenty elders and the four beasts fell down and worshipped God that sat on the throne, saying, Amen; Alleluia” (Revelation 19:4).
“Q. What are we to understand by the four and twenty elders, spoken of by John? A. We are to understand that these elders whom John saw, were elders who had been faithful in the work of the ministry and were dead; who belonged to the seven churches, and were then in the paradise of God” (D&C 77:5).
“What have we to console us in relation to the dead? We have reason to have the greatest hope and consolation for our dead of any people on the earth; for we have seen them walk worthily in our midst, and seen them sink asleep in the arms of Jesus; and those who have died in the faith are now in the celestial kingdom of God. And hence is the glory of the sun” (Joseph Smith, History of the Church 6:315).
“There are two kinds of beings in heaven, namely: Angels, who are resurrected personages, having bodies of flesh and bones . . . Secondly: the spirits of just men made perfect, they who are not resurrected, but inherit the same glory” (D&C 129:1, 3).
Since both resurrected beings and spirits can be in “heaven,” it is possible for a being to be in both “the paradise of God” and “the celestial kingdom of God,” as mentioned in the above quotes.
