In the light of Isaiah 65:17, do you think we will know each other in Heaven?
ANSWER: I would say yes based on II Samuel 12:23, where King David is mourning over the dead child born of his adultery with Bathsheba. He finally consoled himself with, “But now he is dead, wherefore should I fast? Can I bring him back again? I shall go to him, but he shall not return to me.” Also, on the mount of transfiguration, Matthew 17:1-4, Peter, James and John immediately recognized Moses and Elijah.
