We are told in
Ecclesiastes 12:6-7 (KJV) that when our flesh body dies, it goes back to dust from which it came and our spirt - the intellect of our soul - immediately returns to God. There are no qualifications in that scripture about age - it applies to ALL souls. We are also told in
Luke 16 (KJV) that there are TWO SIDES to Paradise (Heaven) separated by a divide or Gulf. The 'bad' side of the Gulf is for those who never had a chance to learn the Truth while on earth or for those who deliberately decided to follow the doctrines of Satan. The 'good' side of the Gulf is where those who have accepted Christ are - awaiting the Millenium period. During the millenium, those souls on the 'bad' side of the Gulf can be visited by their immediate family members from the 'good' side of the Gulf to give them instruction and to show them the Truth of Christ.

Revelation 20:3 (KJV) and
Ezekiel 44:25 (KJV)] Remember - The Book of Ezekiel from chapter 40 to the end takes place IN the Millenium as well as the later chapters of the Book of Revelation.
