Mining scriptural references probably won't help much in this case because we are unavoidably going to draw different conclusions from the verses.
My point, however, is that election requires a choice, by definition.
See Romans 9:11-12:
11 though they were not yet born and had done nothing either good or bad—in order that God's purpose of election might continue, not because of works but because of him who calls—12 she was told, “The older will serve the younger.”
This is indicating God's purpose in election toward Jacob--it is God's choice, not Jacob's or Esau's. I'm not trying to make a theological point with this verse to support unconditional election to salvation; I'm merely pointing out that the term election refers to God's choice.
revmwc, God knew the choices they would make before they were born, so God told her what would happen because He foreknew what would happen.
Also, in the context of choosing (electing) the disciples....
[16] You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide, so that whatever you ask the Father in my name, he may give it to you.
(John 15:16 ESV)
revmwc Christ chose them but when and why, because as scripture says, He told Nanathanial I believe it was Nathaniel, before he called him He saw him standing under a tree a person who in him was no guile. Christ knew them before He called them.
And...
[18] But as it is, God arranged the members in the body, each one of them, as he chose.
(1 Corinthians 12:18 ESV)
And...
[4] even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love [5] he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, [6] to the praise of his glorious grace, with which he has blessed us in the Beloved.
revmwc He chose us because of His foreknowledge, the Omnisicnt God knew us before we were ever born and chose or predestinated us to be members in the body.
(Ephesians 1:4-6 ESV)
And...
[13] But we ought always to give thanks to God for you, brothers beloved by the Lord, because God chose you as the firstfruits to be saved, through sanctification by the Spirit and belief in the truth.
revmwc The first part of Ephesians says whom He did foreknow them He did predestinate, again God chose us because He knew us and the choice of faith we would make.
(2 Thessalonians 2:13 ESV)
When you see these references to "choice," keep in mind that "elect" and "chosen" essentially mean the same thing. The verbs used for "choice" are essentially the verb equivalent forms of the nouns for "elect" and "election."
We can differ on the mechanics of how God chooses, but to deny that God elects (or chooses) in some way is to deny Scriptural teaching.
