"I am God, and there is no other; I am God, and there is none like me, Declaring the end from the beginning and from ancient times things not yet done, saying, “My counsel shall stand, and I will accomplish all my purpose. [calling a bird of prey from the east, the man of my counsel from a far country. I have spoken, and I will bring it to pass; I have purposed, and I will do it.]” (Isaiah 46:10)

The word “sovereignty” (like the word “trinity”) does not occur in the Bible. We use it to refer to this truth: God is in ultimate control of the world from the largest international intrigue to the smallest bird-fall in the forest.
Here is how the Bible puts it: “I am God, and there is no other. . . . My counsel shall stand and I will accomplish all my purpose” (Isaiah 46:9–10). “[God] does according to his will among the host of heaven and among the inhabitants of the earth; and none can stay his hand or say to him, ‘What have you done?’” (Daniel 4:35). “But he is unchangeable, and who can turn him back? What he desires, that he does. For he will complete what he appoints for me” (Job 23:13–14). “Our God is in the heavens; he does all that he pleases” (Psalm 115:3).
One reason this doctrine is so precious to believers is that we know that God’s great desire is to show mercy and kindness to those who trust him (Ephesians 2:7; Psalm 37:3–7; Proverbs 29:25). God’s sovereignty means that this design for us cannot be frustrated.
Therefore, the mercy and the sovereignty of God are the twin pillars of my life. They are the hope of my future, the energy of my service, the center of my theology, the bond of my marriage, the best medicine in all my sickness, the remedy of all my discouragements.
And when I come to die (whether sooner or later), these two truths will stand by my bed and with infinitely strong and infinitely tender hands lift me up to God.
