Abraham Booth on the origin of moral evil

Concerning the origin of moral evil, Abraham Booth writes:

"Were my opinion asked respecting the origin of moral evil, the answer would be, I have no opinion upon the subject: nor dare I form conjectures about it. Having long been fully persuaded, that a satisfactory solution of the question lies far beyond the reach of human intellect; I consider it as more becoming my feeble reason, and much more respectful to Divine Providence, to exclaim with Paul, O the depth! than to indulge in speculation on a subject so mysterious; lest I should fall under the righteous reproof of Jehovah's interrogatory to Job, who is this that darkens counsel by words without knowledge?" (Abraham Booth, Works, Volume 3 from Google Books).

Oh, but you do have an opinion on the subject Mr. Booth! And you proceed hypocritically to "form conjectures about it" by asserting "that a satisfactory solution of the question lies far beyond the reach of human intellect." O the depravity of those like Booth who darken counsel by pseudo-pious platitudes to conceal their ultimate rebellion against Jehovah and His Anointed. O the blindness of those like Booth who indulge in vain speculation on a subject so straightforward and clear.

The salvation that is found exclusively in Jesus Christ is according to God’s eternal purpose (Ephesians 3:11). There are indeed inscrutable mysteries and unfathomable depths (Romans 11:33; cf. Ephesians 3:11-21) concerning God's eternal purpose to glorify Himself in the cross-work of Christ, and in the hearts of His people. But the origin of moral evil is not one of those mysteries since, again, God's eternal purpose was to demonstrate His glory (see Romans 9:18-24).

God made the fall of Adam (and in him his posterity) an inevitable certainty by ordaining and causing it to happen. Many similarly-minded with Booth speak of the fall of Adam and especially the fall of Satan as the “greatest mystery” in all of Scripture. To them, the most profound and perplexing mystery is the origin of moral evil in created beings. To those who submit to the clear testimony of Scripture, it is NOT a mystery at all. God ordained before eternal times to elect and save His people and to actively cause the fall so that He might be glorified in the Person and Work of His Son.

“ ... according to the eternal purpose which He accomplished in Christ Jesus our Lord” (Ephesians 3:11). 

“Then do not be ashamed of the testimony of our Lord, nor of me, His prisoner. But suffer hardship with the gospel, according to the power of God, the One having saved us and having called us with a holy calling, not according to our works, but according to His own purpose and grace given to us in Christ Jesus before eternal times, but now revealed through the appearance of our Savior, Jesus Christ, indeed making death of no effect, bringing life and incorruptibility to light through the gospel, for which I was appointed a herald and apostle and a teacher of nations” (2 Timothy 1:8-11).
“So, then, to whom He desires, He shows mercy. And to whom He desires, He hardens. You will then say to me, Why does He yet find fault? For who has resisted His will? Yes, rather, O man, who are you answering against God? Shall the thing formed say to the One forming it, Why did You make me like this? Or does not the potter have authority over the clay, out of the one lump to make one vessel to honor, and one to dishonor? But if God, desiring to demonstrate His wrath, and to make His power known, endured in much long-suffering vessels of wrath having been fitted out for destruction, and that He make known the riches of His glory on vessels of mercy which He before prepared for glory, whom He also called, not only us, of Jews, but also out of nations” (Romans 9:18-24).
