Calvinism does not survive paying close attention to John 12.
John 12
32 And I, when I am lifted up from the earth, will draw all people to myself."
33 He said this to show by what kind of death he was going to die. 34 So the crowd answered him, "We have heard from the Law that the Christ remains forever. How can you say that the Son of Man must be lifted up? Who is this Son of Man?"
35 So Jesus said to them, "The light is among you for a little while longer. Walk while you have the light, lest darkness overtake you. The one who walks in the darkness does not know where he is going.
(An outward sign of the drawing of all - the light is among you)
36 While you have the light, believe in the light, that you may become sons of light." When Jesus had said these things, he departed and hid himself from them.
(The desired response to drawing is that the ones drawn would choose to believe after being drawn. Christ is not zaaapping them into belief - he is urging them to choose belief in vs 36)
Calvinism's arbitrary selection doctrine does not survive this point.
37 Though he had done so many signs before them, they still did not believe in him,
Here again is illustrated the drawing in outward signs, and also the choice of "some" to not believe (while others obviously chose to believe because of the signs done.)
It is always the "Drawing" that is then followed by the observation of those who choose to accept - vs those who choose to reject.
38 so that the word spoken by the prophet Isaiah might be fulfilled: "Lord, who has believed what he heard from us, and to whom has the arm of the Lord been revealed?" 39 Therefore they could not believe. For again Isaiah said, 40 "He has blinded their eyes and hardened their heart, lest they see with their eyes, and understand with their heart, and turn, and I would heal them." 41 Isaiah said these things because he saw his glory and spoke of him.
42 Nevertheless, many even of the authorities believed in him, but for fear of the Pharisees they did not confess it, so that they would not be put out of the synagogue; 43 for they loved the glory that comes from man more than the glory that comes from God.
So here again we have the choices of man -in response to the "Drawing of all mankind" to Christ.
At no point doe we have "they did not believe because God did not draw them".
