Let me tell you a true story. Earlier this year my wife and I took our two nephews (14 and 6) to the top of Mt. Washington in NH via the Cog Railway. It was a bad weather day on the mountains so we passed through the clouds. At that point the littlest one asked if we were in Heaven. And I replied, "Kind of". He then started waving his hand and saying, "Hi God, I'm here". He had the most innocent beautiful smile I have ever seen and he literally had a glow around his face. A soft shimmering golden glow. So I would say Heaven is (or God's presence) is where ever the simple love and belief of a 7 year child calling out to God is. So yes Virginia there is a real Heaven. As a further note, I believe the "tunnel" all the near deathers talk about is actually a dimension doorway, if you will, that protects us on our journey up from the dimensions Satan and his Ilk rule on our way to heaven. I believe that is why one of Lucifer's titles is, "Prince of Air" . There are stories in the old testament of Angels dealing with demons on a mission to humans.
