D'un point de vue biblique, est-il bon de parler à nos proches qui sont déjà au ciel avec Jésus? 

Question from a reader:

You say in your book that people in Heaven can witness events happening on earth. But what about Isaiah 65:17, which says in heaven “the former things will not be remembered, nor will they come to mind”? Whatever this verse means, it specifically comes after the New Heavens and New Earth, not before. Hence, it has no bearing at all on the question of whether saints presently in heaven can witness events happening on earth.

Yes, people in Heaven have some idea of what’s going on here. They may not know or pay attention to everything that’s happening (like the time you slipped ice into your brother’s pillowcase). But the martyrs in Revelation 6 knew that God hadn’t yet brought judgment on those who killed them, so it’s likely that they knew many other things about what’s happening on earth.
