Individual Election for salvation before creation is precluded by 1 Peter 2:9-10. No one was elected individually before creation, otherwise they would never have not been a chosen people.
1 Peter 1:1-2 teaches our individual election is accomplished by means of being set apart by the Holy Spirit. 2 Thessalonians 2:13, James 2:5 and 1 Corinthians 1:26-30 teach our election is conditional based on faith in the truth, and our love for God. Additionally God's choice was not based on the world's value system, for He did not choose many who were rich, or powerful or of noble birth.
When God chose the Word (Logos) to be His Lamb, His Redeemer, He chose us in Him corporately as the target group of His redemption plan.
Using your own reasoning, we are saved by growth and maturity - "grow up into salvation." This from the exact same passage but a few verses before 1 Peter 2:9-10.
