FYI, I, like most non-Determinists, believe God is in complete Sovereign control of the world which includes as per divine design the ability to create men to have free will/ human volition. I call this Divine Providential Sovereign Control which differs from the Calvinistic philosophical construct that insists God is incapable of Sovereignty over His creation without strict "Deterministic Sovereign Control". Such Deterministic folly not only serves to limit God's abilities to control His creation as divinely designed but unavoidably logically attributes evil to God leading the Calvinist/Determinist into Theological Fatalism.
You guys don't get a monopoly on defining God's Sovereignty.
As I pointed out earlier, you actually don't understand the Calvinist position.
From the 1689 Baptist Confession of Faith 3:1.
--God has decreed in Himself from all eternity, by the most wise and holy counsel of His own will, freely and unchangeably, all things which shall ever come to pass (1).
--Yet in such a way that God is neither the author of sin nor does He have fellowship [i.e. mutual responsibility]
with any (2)
in the committing of sins, nor is violence offered to the will of the creature [no one is made to sin]
nor yet is the liberty or contingency of second causes taken away [i.e. nor is the free working of the law of cause and effect interfered with]
but rather established (3).
--In all this God's wisdom is displayed, disposing all things, and also His power and faithfulness [to His own holy character and His revealed word]
in establishing His decree (4).
(1) Isaiah 46:10; Ephesians 1:11; Hebrews 6:17; Romans 9:15, 18.
(2) James 1:13-15; 1 John 1:5.
(3) Acts of the Apostles 4:27-28; John 19:11.
(4) Numbers 23:19; Ephesians 1:3-5.
Your basic problem is that you are relying on your own fallen human logic, rather than simply believing the word of God.
'Because the foolishness of God is wiser than men, and the weakness of God is stronger than men.'
Jeffrey Dahmer, whoever he may be, did whatever he did because of the wickedness of his own heart, for which he alone was responsible. Yet God was not an impotent bystander, but permitted all such events for His own high purposes (c.f. Romans 8:18-25). I think I read somewhere that about 186,000 people die every day, yet not one of them passes outside of the will of God (Matthew 10:29-31).
