Here you go... From a Mormon perspective, The scriptures below refer to the doctrine of man's potential to become like God. There were even more examples, but I thought these were the most clear.
"Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God:" - Philip. 2:5-6
"I have said, Ye are gods; and all of you are children of the most High." - Psalms 82:6
"The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God. Jesus answered them, Is it not written in your law, I said, Ye are gods?" - John 10:33-34
"The Spirit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together." - Romans 8:16-17
"Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is." - 1 John 3:2
"To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne." - Rev. 3:21
Yeah, I always thought the "Third Heaven" was what you would normally think of as "Heaven" in contrast to the earth's atmosphere or space. I still think that that view is correct but I guess you could squeeze an argument for the three-heavens out of that. Even if you squeeze that out though, it still does not follow that most people will go to one of them, which Mormons do think. Evangelical Chrisitanity, and even the Catholic Church, hold that most people will indeed go to Hell.
Well according to D&C 76 which I provided the link to earlier... The people in the telestial are "they who are cast down to hell and suffer the wrath of Almighty God, until the fulness of times, when Christ... shall have perfected his work." It also says, "we saw the glory and the inhabitants of the telestial world, that they were as innumerable as the stars in the firmament of heaven, or as the sand upon the seashore." Thus, Mormons also believe most people will go to hell, but that the majority will ultimately be delivered by Christ. Mormons use the terms hell and damned in multiple ways. In the broadest use of the terms anyone not in the Celestial glory is damned because they will never be able to receive the eternal blessings available in the Celestial. In a more narrow use of the terms only those in "Outer Darkness" which is not one of the three kingdoms of glory would be considered damned or in hell. This can get confusing so Mormons usually use more specific terms that aren't used in multiple ways within our doctrine.
