Okay, but if challenged you would be forced to reveal your view that Christ died for an elect. I'd find that embarrassing.
...jumping in the middle of a conversation...
Sonnet: So if I call on the name of the Lord, I will be saved?
Lon: That is what scripture says
Sonnet: Does that mean Christ died for me?
Lon: Yes.
Sonnet: How can you say that as a Calvinist? Don't you believe Christ only died for the elect?
Lon: Yes. When I said yes, it was to both your calling on the name of the Lord and Christ dying on the Cross for your sins.
Sonnet: But what if I don't call on His name?
Lon: That would be your decision.
Sonnet: So Christ didn't die for my sins?
Lon: Christ died for the sins of all those who call on the name of the Lord. It may sound circular, but only those who call on the Name of the Lord will be concerned with this. A person who is not moved by the work of Christ will also not care whether Christ died specifically for the or not. I do know, however, that those who do care, Christ specifically died to save them and knew of them when He laid down His life.
My point was that, at the point when the serpent was raised up, every single bitten Israelite was provided for. All those that may have decided that Moses was a crazy and might have refused to look WERE STILL PROVIDED WITH A CURE. They just did not take it. Christ's crucifixion takes this as it's model, for Jesus says so himself.
It is more philosophical at this point: Can God do something and it is not accomplished? Isaiah 46:10 and 55:11 For the Calvinist, if God sets to save all, He saves literally all He can save. Is there effort to save that which will not/cannot be saved? I understand the dissention with us here. As I said, this was a really hard hurdle for me as well. I'm simply trying to effectively answer your question. I also appreciate ensuing questions too, and thank you.
If Christ's provision was limited, then his choice of analogy was poor.
As I said, I may not be classically Calvinist on this point. I simply believe in some ways, at least, the atonement is limited. As with your analogy, those who had already been bitten and died, did not receive the benefit of that bronze serpent. Generally, I believe John 3:16 as 'world' but I recognize that those who died without faith before Christ, weren't included as 'world' as far as I understand.
