This is precisely what Calvin is trying to communicate when he reasons that we are saved by "God's eternal decree, by which He compacted with himself what he willed to become of each man"(Inst. III, 21, 5).
Excellent thought worthy of contemplation. "What He willed to become of each man" is the same as "What He willed each man to be."
He willed an apple to be....(describe apple)
He willed a shark to be....(describe shark)
He willed a lamb to be....(describe lamb)
But, what is a man. In physical form, a human can be described thus and so. In terms of internal workings, humans are so different. All are flawed. Some are forever not so noble.
“What He willed to become of each man”
At its most fundamental level,
Ex. 21:112-13, He that smiteth a man, so that he die, shall be surely put to death. And if a man lie not in wait, but God deliver him into his hand; then I will appoint thee a place whither he shall flee.
Deut. 32:39 See now that I, even I, am he, and there is no god with me: I kill, and I make alive; I wound, and I heal: neither is there any that can deliver out of my hand.
God made man in His own image.
God did NOT make SOME men in His own image--He made ALL men in His own image. This fact alone refutes the double-predestination concept with men having no say in the matter. All men have the ability to make the correct choice.
Some don't--using the free will we were given by the Creator.
You quote Calvin with the same attitude that you abhor
in those who use the teachings of the Roman Catholic
Church. He was just a man yet your attitude manifests
a reverence that only Holy Scripture deserves.
