Now that is very true. But the problem with his will is the nature of his heart. If man's heart is changed, his will will be changed. The only hope of man whose heart is plagued with sin is the complete renovation of his heart by the sovereign power of God. Only a new creation will do the dead sinner good.
Poor sinners are totally unable to change their own hearts.
The Holy Spirit must come in sovereign, lifegiving power, and create the heart anew in Christ Jesus. The new birth is nothing less than a new creation. The Holy Spirit implants within us the new principle of faith which works by love. He gives us a new will, which hungers and thirsts after the righteousness of Christ. Where there was blasphemy, there is praise.
