Calvin - Spontaneous Salvation
It's not hard to find clear gnostic concepts embeded in many of Calvin's teachings and here once again we can see that salvation itself is just spontaneously offered to some.

But if it is plainly owing to the mere pleasure of God that salvation is spontaneously offered to some, while others have no access to it, great and difficult questions immediately arise, questions which are inexplicable, when just views are not entertained concerning election and predestination. To many this seems a perplexing subject, because they deem it most incongruous that of the great body of mankind some should be predestinated to salvation, and others to destruction.
Let's compare this to the Modern Gnostics teachings as we found in the Roots section of this website for they teach this exact process and even

“The advantage of picturing enlightenment as a 2-level system that jumps all at once from complete darkness to complete light is its simplicity of contrast. Perhaps even Calvinism can be seen as both an idealistic 2-level system (in which one is suddenly lifted into his election all at once)"
Now we can compare this to the Scriptural process for coming to salvation.
Romans 10:8-10
8 But what does it say? “The word is near you, in your mouth and in your heart”—that is, the word of faith which we are preaching, 9 that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
