Are Job's seven sons and three daughters in Heaven? At the end of Job, God blessed him and gave him twice as much as he had in the first part of his life but he still has seven sons and three daughters.  Is it a common interpretation that his first seven sons and three daughters who were killed are alive in heaven? This would be twice as much--fourteen sons and six daughters. What are other interpretations from groups that would find the former interpretation unacceptable?
At Acts 2:34 we see that not even David, who was considered to be one of the righteous kings, ascended to heaven. The Bible indicates that Jesus was the first one to be resurrected to spirit life and ascend to heaven. (John 3:13) This would include Job and his sons and daughters. They are still potentially eligible for a resurrection to earthly life during the thousand year reign of Christ. (Job:14:14-15; Acts 24:15; Revelation 20:13)

This is what Jehovah's Witnesses believe. You can read more about the condition of the dead and the hope for the dead in chapters 6 and 7 of the book "What Does the Bible Really Teach?", which you can read for free online.
