I found this on the JW site.
"Jesus said: "No man has ascended into heaven. (John 3:13) He thus showed
that good people who died before him, such as Abraham, Moses, Job, and David,did not go to heaven. (Acts 2:29, 34). Instead, they had the hope of beingresurrected to life on earth.—Job 14:13-15.
A few comments:
a] Why didn't they quote the entire passage? If you include the later partof the verse, then the conclusion is incorrect.
"Moreover, no man has ascended into heaven 'but' the one who descendedfrom heaven, the Son of man."
This does not say that those who died before Jesus will not go to heaven after. And neither does it say that only Jesus will enter heaven after.
b) The Job 14:13-15 reference doesn't say anything about a resurrection to life on only earth.
c) The Acts 2:29,34 reference does not say Abraham and Moses did not go toheaven some time after Christ's resurrection. Luke 13 says "when you seeAbraham, Isaac, Jacob, and all the prophets in the Kingdom of God, but youyourselves [also include every person who is not a child of God] thrown outside." (where there is weeping and gnashing of teeth).
Abraham and Moses are in the Kingdom of God (in heaven).
