Are there other worlds?
God dwells in the infinite, so I would argue that yes, there are other worlds.
There is not much proof for this in the Bible, except for the one verse in Hebrews.
Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds.
- Hebrews 1:2 (KJV)
Plural, but perhaps "worlds" should have been translated as "world", so that's hardly proof for the existence of other worlds.
Or how about these verses from the book of Job that talk about the creation of the world.
Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding. Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it? Whereupon are the foundations thereof fastened? or who laid the corner stone thereof; When the morning stars sang together, and all the sons of God shouted for joy?
- Job 38:4-7 (KJV)
Ellen White confirms that this takes place shortly after the Creation.
In the beginning the Father and the Son had rested upon the Sabbath after Their work of creation. When "the heavens and the earth were finished, and all the host of them" (Gen. 2:1), the Creator and all heavenly beings rejoiced in contemplation of the glorious scene. "The morning stars sang together, and all the sons of God shouted for joy." Job 38:7.
- Ellen White, The Desire of Ages, p. 769
So, there are two groups present here.
- The morning stars
- The sons of God
A "star" means "angel".
The mystery of the seven stars which thou sawest in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven candlesticks which thou sawest are the seven churches.
- Revelation 1:20 (KJV)
So, who then are the sons of God?
But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
- John 1:12-13 (KJV)
For ye are all the children of God by faith in Christ Jesus.
- Galatians 3:26 (KJV)
For as many as are led by the Spirit of God, they are the sons of God.
- Romans 8:14 (KJV)
That's a clear reference to God's people in this world, but it can perhaps also be used to refer to God's people from other worlds.
Adam and Eve weren't created yet when the foundations of the earth were laid, so the sons of God from the verse above (Job) must therefore refer to God's people from other worlds.
So, the angels sang, and God's people from other worlds shouted for joy?!?
That's a bit of a leap. I understand.
But Ellen White does suggest that this is possible.
There is the throne, and around it the rainbow of promise. There are cherubim and seraphim. The commanders of the angel hosts, the sons of God, the representatives of the unfallen worlds, are assembled. The heavenly council before which Lucifer had accused God and His Son, the representatives of those sinless realms over which Satan had thought to establish his dominion,- all are there to welcome the Redeemer. They are eager to celebrate His triumph and to glorify their King.
- Ellen White, The Desire of Ages, p. 834
Ellen White speaks about other worlds in more detail as well.
Then I was taken to a world which had seven moons. There I saw good old Enoch, who had been translated. On his right arm he bore a glorious palm, and on each leaf was written "Victory." Around his head was a dazzling white wreath, and leaves on the wreath, and in the middle of each leaf was written "Purity," and around the wreath were stones of various colors, that shone brighter than the stars, and cast a reflection upon the letters and magnified them. On the back part of his head was a bow that confined the wreath, and upon the bow was written "Holiness." Above the wreath was a lovely crown that shone brighter than the sun. I asked him if this was the place he was taken to from the earth. He said, "It is not; the city is my home, and I have come to visit this place." He moved about the place as if perfectly at home. I begged of my attending angel to let me remain in that place. I could not bear the thought of coming back to this dark world again. Then the angel said, "You must go back, and if you are faithful, you, with the 144,000, shall have the privilege of visiting all the worlds and viewing the handiwork of God."
- Ellen White, Christian Experience and Teaching, p. 98.2
But not everybody will believe that of course, so we remain stuck with this question about other worlds.
My opinion is that our world is under quarantine, so no other worlds are allowed to come near us at this time.
