Heb 1:2
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;
Heb 11:3
Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
Worlds, plural, more than one. Then:
Isa 45:18
For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else.
I don’t think He created the other worlds in vain either – he formed them to be inhabited as well.
Ephesians 3:9
And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ: Ephesians 3:10
His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms, Ephesians 6:12:
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Job 38:7
When the morning stars sang together, and all the sons of God shouted for joy?
