I know that when children die they go to Heaven and that when the Rapture occurs the children will go to Heaven but do they remain children when they get to Heaven and mature there or do they stay children forever or do they immediately become adults when they get to Heaven? Which brings to mind another question, when we die and go to Heaven do we stay the same age as we were when we died or does everyone become a certain age for eternity?
Whether children who die or are raptured immediately become adults or not is an issue the Bible doesn’t address. As for aging, time will pass during the Millennium, but how this affects eternal bodies is not described. It appears that even natural bodies on earth will age more slowly. Isaiah 65:20 says that a person who dies at age 100 will be thought a mere youth. For any additional detail, we’ll just have to wait and see.
