And since we cannot it must occur by God's will.
Indeed. It is by God's Powerful Will, and it is also by His Powerful Right Arm of Salvation (who has always been Christ). To receive a new heart and Spirit is the Purpose of Christ, the Work of Christ, and these two things lead to the Holy Effect of Christ. It is the Lord's Plan:
Ezekiel 36:25-27 NLT - "Then I will sprinkle clean water on you, and you will be clean. Your filth will be washed away, and you will no longer worship idols. And I will give you a new heart, and I will put a new spirit in you. I will take out your stony, stubborn heart and give you a tender, responsive heart. And I will put my Spirit in you so that you will follow my decrees and be careful to obey my regulations."
The Apostle Paul explains this process outlined above as he shows us the Gospel in and through the Work of Christ. Colossians 2:9-15 is so clear in its teachings that we should be able to make the connection between Ezekiel 36:25-27 and Colossians 2:9-15. Colossians 2:9-15 explains Ezekiel 36:25-27.
Colossians 2:9-15 NLT - "For in Christ lives all the fullness of God in a human body. So you also are complete through your union with Christ, who is the head over every ruler and authority. When you came to Christ, you were "circumcised," but not by a physical procedure. Christ performed a spiritual circumcision--the cutting away of your sinful nature. For you were buried with Christ when you were baptized. And with him you were raised to new life because you trusted the mighty power of God, who raised Christ from the dead. You were dead because of your sins and because your sinful nature was not yet cut away. Then God made you alive with Christ, for he forgave all our sins. He canceled the record of the charges against us and took it away by nailing it to the cross. In this way, he disarmed the spiritual rulers and authorities. He shamed them publicly by his victory over them on the cross."
Or, we can add more from the Old Testament. This one should blow our minds as well.
Deuteronomy 30:6 NLT - "The LORD your God will change your heart and the hearts of all your descendants, so that you will love him with all your heart and soul and so you may live!"
I'm not the one writing these things! I'm not the one saying them! I am only copying and pasting the Holy Word of God. No one should EVER ridicule another for taking the stance that the "free will" concept has some gaping black holes in it. We have clear and obvious reasons for believing what we believe.
