Dune's question can be found here: http://www.jehovahs-witness.net/jw/friends/172061/1/
He says:
One time, this elder told me that we wouldn't have genitals in the paradise, hence, the reason we wouldn't be able to/be having any children there. This kind of sorta led me into doing research for myself, instead of taking the elder's words for things.
Verily, that ELDER spoke purest TRUTH! Witness this:
• Do Jesus’ words at Luke 20:34-36 apply to the earthly resurrection or to the heavenly resurrection of the 144,000?—W. D., Australia.
...How, then, will those raised to earthly life be like the angels? The angels in heaven do not marry and procreate, producing angelic offspring. Yet they can enjoy satisfying association with myriads of other spirit creatures serving God. Similarly, those who in this present wicked system of things prove themselves worthy of gaining a resurrection in the new order or the coming system of things will not marry and produce offspring. (2 Cor. 4:4; Mark 10:30) Immediately upon resurrection they become “God’s children by being children of the resurrection.” Their heavenly “Father,” the one giving them life by resurrecting them, has determined that they will not marry, though they will be in position to receive many other blessings at his hand, not the least of which will be the privilege of close and warm association with other earthly servants of God. - The Watchtower, October 15, 1967, page 639, "Questions from Readers"
