I skipped writing on chapter 5 which was entitled the Supremacy of God because this chapter is "described as the exercise of his supremacy." Here's a few quotes.
"Divine sovereignty means that God is God in fact, as well as in name, that he is on the Throne of the universe, directing all things, working all things "after the counsel of his own will" (Eph. 1:11)."
"There is no attribute more comforting to His children than that of God's Sovereignty. Under the most adverse circumstances, in the most severe trials, they believe that Sovereignty has ordained their afflictions, that Sovereignty overrules them, and that Sovereignty will sanctify them all. There is nothing for which the children ought more earnestly contend than the doctrine of their Master over all creation- the Kingship of God over all the works of His own hands- the Throne of God and His right to sit upon that Throne."-C.H. Spurgeon
"He will is supreme. So far from God being under any law of "right", he is unto himself, so that whatsoever he does is right. And woe be to the rebel that calls his sovereignty into question: "Woe unto him that striveth with his Maker. Let the potsherd strive with the potsherds of the earth. Shall the clay say to him that fashioned it, What makest Thou?" (Isa. 45:9)."
"Many have most foolishy said that it is quite impossible to show where Divine sovereignty ends and creature accountability begins. Here is where creature responsibility begins: in the sovereign ordination of the Creator. As to his sovereignty, there is not and never be any "end" to it!"
"Here, then, is the highest and grandest display of the absolute sovereignty of God. Verily, he has "mercy on whom he will have mercy, and whom he will he hardeneth" (Rom. (:18)."
