Sorry, the does not refute God had from the beginning chose them for salvation.
No mention of any "plan"
You did nothing to address this
Sorry but there was no running off
verses 1, 3, 4 in context, and verse 13 were all addressed and shown to refute your claim
and you just dismissed it
That is nothing more than denial
I noted two possibilities how men can be chosen before the foundation of the earth without unconditional election and you just ignore them
the "you" are believers - those in Christ
Context matters
Ephesians 1:1 (ESV) — 1 Paul, an apostle of Christ Jesus by the will of God,
To the saints who are in Ephesus, and are faithful in Christ Jesus:
Nothing there states they were men unconditionally chosen. Your theology just assumes that
You do not address this
all their blessing are in Christ
Ephesians 1:3 (ESV) — 3 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places,
You did not address this
it is in Christ they are chosen to be holy and blameless
Ephesians 1:4 (ESV) — 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
so they have to be in Christ before being chosen
You did not address this either
Now this could either be based on God's foreknowledge
or his corporate election where he determined all in Christ would be chosen to be holy and blameless
but it cannot be unconditional because all those blessing are in Christ
You did not address this either
and one is not in Christ until he believes trusts in Christ
Ephesians 1:13 (ESV) — 13 In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit,
and that transpires in time
Romans 16:7 (ESV) — 7 Greet Andronicus and Junia, my kinsmen and my fellow prisoners. They are well known to the apostles, and they were in Christ before me.
