“Why did God create?…God was not inwardly lonely or personally empty; He was entirely self-satisfied, self-content, and self-contained. So God did not create because of some limitation within Himself…
He created everything out of nothing in order to put His glory on display for the delight of His created beings and that they might declare His greatness.
…A. W. Pink writes with thought-provoking wonder of the extraordinary sovereignty of God before creation:
‘In the great expanse of eternity, which stretches behind Genesis 1:1, the universe was unborn and creation existed only in the mind of the great Creator. In His sovereign majesty God dwelt all alone…There were then no angels to hymn God’s praises, no creatures to occupy His notice, no rebels to be brought into subjection. The great God was all alone amid the awful silence of His own vast universe. But even at that time, if time it could be called, God was sovereign. He might create or not create according to His own good pleasure. He might create this way or that way; He might create one world or one million worlds, and who was there to resist His will? He might call into existence a million different creatures and place them on absolute equality, endowing them with the same faculties and placing them in the same environment; or, He might create a million creatures each differing from the others, and possessing nothing in common save their creaturehood, and who was there to challenge His right? If He so pleased, He might call into existence a world so immense that its dimensions were utterly beyond finite computation; and were He so disposed, He might create an organism so small that nothing but the most powerful microscope could reveal its existence to human eyes. It was His sovereign right to create, on the one hand, the exalted seraphim to burn around His throne, and on the other hand, the tiny insect which dies the same hour that it is born. If the mighty God chose to have one vast graduation in His universe, from loftiest seraph to creeping reptile, from revolving worlds to floating atoms, from macrocosm to microcosm, instead of making everything uniform, who was there to question His sovereign pleasure?’
God’s dazzling display of sovereignty in creation was a primer (an introductory teaching on a complicated subject) on His right to rule in matters of salvation. God, who commanded the light to appear on day one of creation, soon would order gospel light to shine into the darkened hearts of spiritually blind sinners. God, who separated the waters on day two, would cause an infinite chasm to separate Himself from sinners. God, who gathered the waters together on day three, would gather sinners to Himself. God, who created the sun, moon, and stars on day four, would omnipotently create saving faith. God, who began to create the animal kingdom on day five, would graciously send His Son to be the Lamb of God to take away sin. God, who created Adam and Eve on day six, would soon re-create sinners into His image. His free grace would perform the second Genesis in the salvation of lost men and women.” (From Foundations of Grace by Steven Lawson – this excerpt from July 3, 2017’s “Why did God create?” at ligonier.org)
