So what moved you to come to Jesus then, your choosing Him first, or God first choosing you?
Why not address the verses referenced and indicate their validity. Why change the subject, and not seek reconciliation?
But because I actually seek to come to a common understanding, I will once again answer your questions.
God formulated His redemption plan before creation. He chose God the Son to be His Redeemer, His Lamb of God before the foundation of the world. And you do not choose a Redeemer unless you plan on redeeming. Thus every born anew believer was chosen corporately before the foundation of the world.
However, no one was chosen individually until God sets them apart in Christ (the sanctification by the Spirit) based on God crediting their faith in the truth as righteousness.
Y1, you can deny being chosen in Him refers to a corporate election.
Y1, you can deny the Lamb of God was chosen before the foundation of the world.
Y1, you can deny that from the foundation of the world refers to a different period than before the foundation of the world.
Y1, you can deny God credits our faith in Christ as righteousness.
Y1, you can deny we are chosen for salvation through faith in the truth.
Unless you address scripture and provide an alternate interpretation of all these verses, it is difficult to respond.
