If God does not have pleasure in the death of the wicked and he changes the heart irresistibly then why doesn't he change everyones heart irresistibly?
Eze 33:11 Say unto them, As I live, saith the Lord GOD, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn ye, turn ye from your evil ways; for why will ye die, O house of Israel?
He has no pleasure (does not take delight) in the death of the wicked, but has pleasure (takes delight) in the wicked turning from his way and living.
A judge takes no delight in sentencing a murderer to death, but justice requires it. The same judge would take delight in seeing the murderer express remorse over his crime, but justice would still require his blood. A human judge has no ability to allow someone else to bear the sentence in the murderer's place, but God does; His Son. The blood requirement of justice is still met, but by the Blood of Jesus in the place of the murderer's.
If God desired, He could cause every sinner to turn from his wickedness and believe on His Son (or do you deny that He is able to do that?), but obviously He does not do that. There must be a reason why He doesn't that is more important than that He takes no delight in the death of the wicked. That reason, in my estimation, would have to be that His glory requires the death of the wicked to be adequately displayed.
The wickedness of our hearts is far more unholy and despicable in contrast to God's holiness than our sin-warped little minds can understand, and the multitude of vessels of wrath are a testimony to that fact.
The glory of His grace is displayed in the vessels of mercy, and that too is far beyond our comprehension, that He would go to such amazing lengths to reconcile to Himself a remnant out of such a cesspool of sin.
What you are doing is confusing two things that are categorically different. What He takes delight in is a category that does not rise to the importance of the category of His glory.
Another important aspect is that this statement is addressed to the wicked of covenant Israel, not to all the wicked of the world. That He takes no delight in the unrepentance of His covenant people will not prevent Him from displaying the glory of His righteous judgement by their destruction.
Pro 16:4 The LORD hath made all things for himself: yea, even the wicked for the day of evil.
