The Bible does not specifically say whether or not people in heaven can look down on us who are still on the earth. It is highly unlikely that they can. Why? First, they would sometimes see things that would cause them grief or pain, namely, acts of sin and evil. Since there is no grief, tears, or unhappiness in heaven (Revelation 21:4), it does not seem that observing earthly events would be possible. Second, people in heaven are so preoccupied with worshipping God and enjoying the glories of heaven that it does not seem they would have significant interest in what is happening here on earth. The very fact that they are free from sin and experiencing God’s presence in heaven surely is more than enough to captivate their attention. While it is possible that God allows people in heaven to look down upon their loved ones, the Bible gives us no reason to believe this actually occurs.
Can people in heaven look down and see us?
I normally agree with most of what that site has to say, but in this instance I earnestly think they get it wrong.
I hadn't thought of the Hebrews passage. They do a poor job of explaining why they interpret it the way they do. The only other Scripture they use is Revelation 21. I've got news...do you think that Revelation 21 has happened yet?
EDIT: (I do happen to believe that Hebrews describes what I am talking about BTW)
Notice how that chapter opens:
Revelation 21:1-4
1Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea. 2I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. 3And I heard a loud voice from the throne saying, "Now the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God. 4He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away."
Emphasis mine.
So, have the old earth and the old Heaven passed away already?
Let's look back a little further in Revelation 6:
9When he opened the fifth seal, I saw under the altar the souls of those who had been slain because of the word of God and the testimony they had maintained. 10They called out in a loud voice, "How long, Sovereign Lord, holy and true, until you judge the inhabitants of the earth and avenge our blood?" 11Then each of them was given a white robe, and they were told to wait a little longer, until the number of their fellow servants and brothers who were to be killed as they had been was completed.
This is the passage I was thinking of. However upon closer examination, I think it doesn't really say one way or the other. Although I would think if the Saints are still beseeching God for justice and vindication that He hasn't judged the world yet and hence Revelation 21 hasn't happened yet. The Great White Throne judgment must come before the new heaven and new earth.
We see one other passage in Revelation dealing with the state of those in heaven.
Revelation 7
13Then one of the elders asked me, "These in white robes—who are they, and where did they come from?"
14I answered, "Sir, you know."
And he said, "These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the Lamb. 15Therefore,
"they are before the throne of God
and serve him day and night in his temple;
and he who sits on the throne will spread his tent over them.
16Never again will they hunger;
never again will they thirst.
The sun will not beat upon them,
nor any scorching heat.
17For the Lamb at the center of the throne will be their shepherd;
he will lead them to springs of living water.
And God will wipe away every tear from their eyes."
Notice the future tense of this passage?
Not trying to tear down anybody's view of heaven, but just trying to point out a logical fallacy.
