Many seem to have the idea that this world and the heavenly mansions constitute the universe of God. Not so.75SDA Bible Commentary 7:990.
God has worlds upon worlds that are obedient to His law. These worlds are conducted with reference to the glory of the Creator. As the inhabitants of these worlds see the great price that has been paid to ransom man, they are filled with amazement.76The Review and Herald, September 25, 1900.
The Lord has given me a view of other worlds. Wings were given me, and an angel attended me from the city to a place that was bright and glorious. The grass of the place was living green, and the birds there warbled a sweet song. The inhabitants of the place were of all sizes; they were noble, majestic, and lovely. They bore the express image of Jesus, and their countenances beamed with holy joy, expressive of the freedom and happiness of the place.
I asked one of them why they were so much more lovely than those on the earth. The reply was, “We have lived in strict obedience to the commandments of God, and have not fallen by disobedience, like those on the earth.” Then I saw two trees, one looked much like the tree of life in the city. The fruit of both looked beautiful, but of one they could not eat. They had power to eat of both, but were forbidden to eat of one. Then my attending angel said to me, “None in this place have tasted of the forbidden tree; but if they should eat, they would fall.”
Then I was taken to a world which had seven moons. There I saw good old Enoch, who had been translated.... 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.” 77Early Writings, 39-40. Mar 368
Again, Christ had truths to present which the people were unprepared to accept or even to understand. For this reason also He taught them in parables. By connecting His teaching with the scenes of life, experience, or nature, He secured their attention and impressed their hearts. Afterward, as they looked upon the objects that illustrated His lessons, they recalled the words of the divine Teacher. To minds that were open to the Holy Spirit, the significance of the Saviour's teaching unfolded more and more. Mysteries grew clear, and that which had been hard to grasp became evident. COL 21
Thus saith the Lord.... I, even my hands, have stretched out the heavens, and all their host have I commanded. Isaiah 45:11-12. KJV
