I agree with those verses.
If you can make yourself a good vessel, then you will be accepted. How many make themselves a good vessel?
Even such verses should cause the person to realize their utter helplessness before God to make themselves into a good vessel.
Yet, the free-willer will proclaim that he has, in fact, done that.
By the way, Ezekiel 18 is about some Israelites in captivity. Their ancestors had sinned, and as a consequence, they were in captivity. Their attitude was, what's the use? Our parents have already caused us to be exiled so we might as well sin all we want because our sins don't matter. God was saying, in essence, this isn't the right attitude. You need to be focused on your sinfulness, and correct it.
However, what would that require? It would require a new heart. Who gives them that new heart? God. Who is he going to give it to? The elect. There were elect individuals within the group who would respond to this urging because God gives them the new heart. The rest are going to continue in their sinfulness, but they were informed of God's command to repent, regardless if they responded or not.
Natural man won't respond. He needs a heart change to respond in faith and repentance. This heart is needed to exercise both, and in fact, are gifts brought about by God.
Y
our free-will view teaches that in order to receive this new heart, you need to respond in faith and repentance. This is called decisional regeneration. However, you can't repent and put your faith in Christ, because you have a hard heart.
Free-willers can keep their defective theology that causes them to boast about their free-will decisions. I know the truth.
