I’m not being clear, my apologies.
I don’t mean to say that in Calvinism, you know specifically who is born reprobate and who is born elect. But that some are born reprobate and forever reprobate.
This would be a true statement, yes?
What you are implying is that some people are born elected and some are born reprobates, which is not technically correct. All people are born in a fallen, wicked state. God, by His grace and mercy, elects some people according to His divine purpose that has nothing to do with what we do. Moses, Jeremiah, Abraham, Paul are a few examples of God coming to them, not them coming to God.
The rest God passes by; why we don't know. Two people hear the same sermon, one believes and one doesn't. God gave one faith. The other He did not. There is nothing that we have that hasn't been given to us. That is how God works.
Everyone God wants saved will be saved.
