Will there be children in heaven?
Thank you for your question. I believe that there is one specific and very definitive passage that indicates that there are children in heaven. In 2 Samuel 12:22-23, King David had been mourning the death of his newborn son. He said, “While the child was still alive, I fasted and wept. I thought, ‘Who knows? The LORD may be gracious to me and let the child live.’ But now that he is dead, why should I go on fasting? Can I bring him back again? I will go to him, but he will not return to me.”
When David says, “… I will go to him …,” he is referring to the event of his own death (as a believer) at some point in the future. When he dies, he will immediately be in God’s presence in Heaven, so this must be where his son already is.
We can also infer from this that when a believer dies, he will be able to see all other believers (who have died) in heaven, including those who died as infants, and those who died in old age. However, it’s difficult for us to imagine the concept of age in heaven, since it’s an eternal state that is not bound by space or time.
I hope this makes sense. If not, please let me know.
