A. W. Pink describes the sovereignty of God this way –
The Sovereignty of the God of Scripture is absolute, irresistible, infinite. When we say that God is Sovereign we affirm His right to govern the universe which He has made for His own glory, just as He pleases. We affirm that His right is the right of the Potter over the clay, i. e., that He may mold that clay into whatsoever form He chooses, fashioning out of the same lump one vessel unto honor and another unto dishonor. We affirm that He is under no rule or law outside of His own will and nature, that God is a law unto Himself, and that He is under no obligation to give an account of His matters to any.
Sovereignty describes the infinite authority and rule of God in heaven and earth. This attribute of God must be first because if we cannot understand that God is sovereign in all things then we will not accurately understand anything else about him.
Genesis 12 states:
Now the Lord had said to Abram: “Get out of your country, from your family and from your father’s house, to a land that I will show you. I will make you a great nation; I will bless you and make your name great; and you shall be a blessing. I will bless those who bless you, and I will curse him who curses you; and in you all the families of the earth shall be blessed.” (vs. 1-3)
This famous text demonstrates we are dealing with the sovereign Lord. Not only does God command Abram, he adds what he will do in the entire earth. We take it for granted because we are familiar with the passage. But this type of interaction shows us who we are dealing with. The command comes from the Sovereign and includes what he will do in the earth. We have forgotten who God is due to vague familiarity and we take for granted who he truly is. As Pink aptly points out, God is a law unto himself and is not obligated to explain his actions and decrees. The blessing through Abraham was not fully seen until centuries later through Christ and literally continues to be fulfilled. This is how big God is and why we must affirm his sovereignty in all things. Abram did not decide to bless the nations, nor can we push God aside with our man-made sovereignty.
To understand God, we must first comes to grips with his absolute sovereignty. When we move our focus away from ourselves and see the mind-blowing authority of Adonai Yahweh, then we can humbly draw close to him and understand the revelation of who he is.
For His dominion is an everlasting dominion,
And His kingdom is from generation to generation.
All the inhabitants of the earth are reputed as nothing;
He does according to His will in the army of heaven
And among the inhabitants of the earth.
No one can restrain His hand
Or say to Him, “What have You done?” Daniel 4:34-35
