it seems the John 10 text was used to suggest a type of election because Jesus said "you believe not because you are not of my sheep." Could not Jesus enable them to believe at a later time or was that statement a constant condition they could never receive Salvation? I do not believe the text is saying that yet it is used by some Calvinists as supporting text for Election.
[Jhn 10:3 KJV] 3 To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out.
Also, I'd also like to expound on something I said in my prior post to you - the promise of God. Because salvation is God's promise to Abraham (Gal 3:29), it being His promise, cannot be dependent upon anything that man might or might not do, but only and solely dependent upon God's actions. Otherwise, the promise would not have been made by Him because He could not have guaranteed the results. Therefore, all who become saved are saved because of His choice of them individually, from/by that promise.
