From an interview with Ashley Null (author of Thomas Cranmer's Doctrine of Repentance: Renewing the Power to Love):
According to Cranmer’s anthropology, what the heart loves, the will chooses, and the mind justifies. The mind doesn’t direct the will. The mind is actually captive to what the will wants, and the will itself, in turn, is captive to what the heart wants.
The trouble with human nature is that we are born with a heart that loves ourselves over and above everything else in this world, including God. In short, we are born slaves to the lust for self-gratification, i.e., concupiscence. That’s why, if left to ourselves, we will always love those things that make us feel good about ourselves, even as we depart more and more from God and his ways.
Therefore, God must intervene in our lives in order to bring salvation. Working through Scripture, the Holy Spirit first brings a conviction of sin in a believer’s heart, then he births a living faith by which the believer lays hold of the extrinsic righteousness of Christ. Of course, the perfect justifying righteousness by which we are made right with God must be outside of us, for the ongoing presence of sinful concupiscence in our mortal bodies renders it impossible for us ever to be truly holy in this life. Indeed, the glory of God is his love for the unworthy, that although we are sinners, he makes us his own.
Now, in effect, justification gives us a heart transplant. For at the same time that we receive the gift of justifying faith by which we are credited with Christ’s extrinsic righteousness, God also sheds abroad in our hearts a new love for him and one another. This new heart love for him, from him, naturally redirects our wills away from sinful selfishness towards a life lived in thankful obedience to God’s commands. Even though we continue to have to struggle with the pull of concupiscence in our mortal bodies, the the supernatural power of God’s abiding love has fundamentally changed us. (HT Mockingbird)
I'd tweak that as I think the heart/mind/will view of humanity over-simplifies how we work (anyone know the origins?), but if you're going to use those categories then I do think that this is the best way to relate them. I have a post brewing centred on this theme waiting till after tomorrows exam!
