[When one turns to the Lord in this manner, is it not the Lord Himself that removes the veil and heals that deficiency? I don't think what you have stated would necessarily contradict what I said.]
The Lord removes the veil when WE turn to the Lord. The response must always be ours.
Paul had his blindness removed in a very direct way without mentally turning to the Lord first (or at least none is mentioned). God seemed to very directly turn Paul to Himself, but it was in Paul's spiritual nature to accept God when blindness was removed.
Paul's blindness was removed when He accepted His acceptance in Christ, that is, he had to say yes to Jesus first.
[The whole debate about determinism vs free will reminds me of the Euthyphro dilemma. Does God love something because it is pious or is something pious because God loves it? Which comes first? A commonly accepted solution to the dilemma is that both are one in the same and that neither has primacy over other.]
You are now becoming nebulous by trying to confuse the issue. Please stay focused on the scriptures.
[If we apply that solution to this question of free will vs determinism, we see it fits in a similar way: did we choose God because it is part of our God-given nature? Or is that God-given nature the result of our choice? The solution would really be that they are one and the same.]
You have entered now into a faithless discussion where the Lord has been set aside to try to prove a theory.
[The complication to this is that those called to Christ exist in a duality of sinful nature and God-seeking nature. We have a choice over "which wolf to feed" and Paul touches on this topic when he talks about his own covetousness.]
Sinful nature is not biblical. Try again. There is nothing in the scriptures that speak of a sinful nature.
[Not everyone has an inherent God-seeking nature (the tares). So even with a blindness lifted, these people will not seek God.
Thoughts on this?]
No one seeks after God for all are corrupt, but that does not mean men can be redeemed. The fact is that no one is or will be interested in the Lord UNLESS the Lord draws them to Himself, however, the Lord works with everyone the same way, but only those who begin to respond are able to see their need for salvation. The Lord draws them until they see their need for redemption. BUT for those who harden their hearts, God continues to work to soften them, but if they persist as Pharaoh did, God will harden their hearts right up to their moment of death. Self-will can be deadly.
Now for more scriptures:
2 Corinthians 3:16 (NASB95) "but whenever a person turns to the Lord, the veil is taken away."
But whenever a person turns to the Lord, the veil of blindness is taken away. How does a person turn to the Lord? By hearing the word of God, the gospel. The answer lies in OUR RESPONSE TO THE GOSPEL.
God does not coerce, nor does He take sides nor is He PARTIAL to anyone!
Acts 10:34 (NASB95) "Opening his mouth, Peter said: “I most certainly understand now that God is not one to show partiality."
Romans 10:8–10 (NASB95) "But what does it say? “The word is near you, in your mouth and in your heart”—that is, the word of faith which we are preaching,
9 that IF YOU confess with your mouth Jesus as Lord, and BELIEVE IN YOUR HEART that God raised Him from the dead, you will be saved;
10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation."
Romans 10:12–13 (NASB95) "For there is no distinction between Jew and Greek; for the same Lord is Lord of all, abounding in riches for all who call on Him;
13 for “Whoever will call on the name of the Lord will be saved.”
