Summary, the biblical doctrine of individual election for salvation is conditional, it occurs during our lifetime; God chooses us individually out of this world, not before the foundation of the world, when He chose Christ.
The only way I see to reconcile Ephesians 1:4, He chose us in Him before the foundation of the world, with 2 Thessalonians 2:13, and John 15:19 and 1 Peter 2:9-10 and James 2:5 is to understand the phrase “He chose us in Him” as meaning He chose Christ to be His Redeemer, His Lamb of God (1 Peter 1:20) before the foundation of the world, and since you do not choose a Redeemer without a plan to redeem, God’s choice of Christ chose us corporately as a target group of His Redemption plan but not individually. Thus Paul (in Ephesians 1:4) is speaking to those who have been redeemed during their lives, and is letting them know of the many blessings they have received, the first one being the blessing that was directed toward them when God chose Christ.
How can anyone claim we were "children of wrath" if we had received mercy before we existed? Once we are set apart in Christ we are children of God, a new creation.
