No, that would be Jacobus Arminius. And it was then just as it is now, because of hard-headedness and pride. Yes, Jacobus Arminius has influenced many, many people down through the centuries, especially people in the West.
The only thing John Calvin might have been (because we don't really know) really frustrated about was the obstinance and blindness of others.
LOL! We all struggle with doubt, frustration, and anxiety regarding all sorts of things. But with regard to the Bible, John Calvin obviously had no lack of confidence.
That's not what he preached at all. He did preach the sovereignty of God, but that's an immutable truth of God's Word... a quality of God that is indisputable. As Job says,
"(God's) purposes cannot be thwarted" (Job 42:2). And as Paul says:
"Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways! “For who has known the mind of the Lord, or who has been his counselor? Or who has given a gift to him that he might be repaid?' For from him and through him and to him are all things. To him be glory forever. Amen." (Romans 11:33-36)
Neither said that in any way, shape or form.
"...the intention of man's heart is evil from his youth" (God Himself, Genesis 8:21)
"...the hearts of the children of man are full of evil, and madness is in their hearts while they live, and after that they go to the dead" (Ecclesiastes 9:3)
"All we like sheep have gone astray; we have turned—every one—to his own way; and the LORD has laid on him the iniquity of us all" (Isaiah 53:6).
They didn't teach this, either. What people should be able to do is to distinguish autonomy from mere free will. Many will not do this, and that's the cause of their lack of understanding.
Well, now this is interesting. What they preached was the majesty and the splendor of God. Yes, there is a sadness to be aware of here, but that is that, out of pride and perceived offense, some still see God as monstrous and hold Him in contempt.
No one is forced to do anything. Everyone gets what he/she wants. But God did make each one for a specific purpose, for sure. This is His right as Creator. He is the potter and we are the clay:
"But who are you, O man, to answer back to God? Will what is molded say to its molder, 'Why have You made me like this?' Has the potter no right over the clay, to make out of the same lump one vessel for honorable use and another for dishonorable use? What if God, desiring to show His wrath and to make known Yis power, has endured with much patience vessels of wrath prepared for destruction, in order to make known the riches of His glory for vessels of mercy, which He has prepared beforehand for glory ~ even us whom He has called, not from the Jews only but also from the Gentiles?”
Nowhere does Paul say we do not make a choice regarding God and His salvation, and even a free-will choice (there is no other kind of choice) at that. In fact, the strong implication is that we absolutely do make a free-will choice. But it
depends on God, which is exactly what Paul says earlier in Romans 9, namely verse 16.
Nope. And nope. But he did believe in a Right and a wrong.
Grace and peace to you.
