1) "What was Israel seeking for
and
2)What is the reason they did not obtain it according to the context?
and
3) How did the elect obtain it. according to the context?"

God always has a remnant.
Scripture interprets Scripture, as we can see in John 12 39-40 why they (Israel a nation made up of people, Jews) could not believe, because God blinded their eyes and hardened their hearts nor could they understand with their heart.

In Romans 11:7-8 We see that there was a remnant among the Jews that were elected by God and the rest of Israel(nation of people, Jews) were blinded by God.

These portions of Scripture agree together in that the majority of Israel as a nation of people (Jews) were blinded by God and did not obtain that which they seeked for but that only a remnant of the Jews obtained mercy, grace, life, and righteousness in Christ.

"42 Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue:"

This is how I reconcile it.

If Jesus draws all men (every man without exception) unto himself and the Father was drawing the Jews to Jesus as the Messiah of Israel why does it say in John 12:39 that they could not believe because God had blinded their eyes and hardened their heart?

The words “Draw and Drew” in the verses below are the greek word “Helkuo” and is found 8 times in the New Testament.

"Helkuo" means, literally, "to drag."

Joh 6:44
No man can come to me, except the Father which hath sent me
***draw*** him: and I will raise him up at the last day.

Joh 12:32
And I, if I be lifted up from the earth, will ***draw*** all men unto me.

Joh 18:10
Then Simon Peter having a sword ***drew*** it, and smote the high priest's servant, and cut off his right ear. The servant's name was Malchus.

Joh 21:6
And he said unto them, Cast the net on the right side of the ship, and ye shall find. They cast therefore, and now they were not able to ***draw*** it for the multitude of fishes.

Joh 21:11
Simon Peter went up, and ***drew*** the net to land full of great fishes, a hundred and fifty and three: and for all there were so many, yet was not the net broken.

Act 16:19
And when her masters saw that the hope of their gains was gone, they caught Paul and Silas, and ***drew*** them into the marketplace unto the rulers,

Yes, His own were once wicked sinners but God loved His own while they were yet sinners. Paul is speaking to the church in Rome, the beloved of God.

Rom 5:8
(8) But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.

“The metaphorical use of "to draw" is consistently used in Scripture and in language in general to attact, allure, or woo.”

Where do we see instances of God trying to reach Pharaoh?

Did you think that when we said that repentance is from God that we don't repent?

God is love and He is just but God also states that He hates. Are you saying that God does not hate?

You think the verses below are speaking of the future judgement to come??

You need the Spirit of God to understand the gospel as the natural man cannot.

Mark 4:12 is not saying that at any time they may be converted, those who do not have the Spirit. It is a judgement from God a judicial blindness which Isaiah prophesied of in Isaiah 6:9,10.

Isa 6:9-10
(9) And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.
(10) Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed.
