In the Reformed tradition, how does an elect understand progressive healing of reason, emotion, and will before death?

Reformed tradition teaches that human beings are [totally depraved](https://www.focusonthefamily.com/family-qa/the-fall-of-man-and-total-depravity/) , and cannot even come to faith without God's assistance. Their *reason* rejects God's supremacy, their *will* refuses God's invitation, and their *emotion* recoils against God's goodness. This is because human beings are born "in Adam", who "died" spiritually because of the Fall and we live under the power of sin. But once God "breathes" spiritual life into the elect, and the elect then comes to faith and becomes conscious of his/her new status in Christ, the elect is now in the *sanctification* stage working with the grace of the Holy Spirit to become more and more reformed in character. Then after death, in the elect's *glorification* stage I assume he/she will live eternally like the perfect human Jesus with *full functioning reason, will, and emotion as originally created in the image of God*, similar to how Jesus lived on earth without original sin (see [Nathaniel's answer to another question](https://christianity.stackexchange.com/a/61910/10672)) . My question is: **since we are in the "*already, but not yet*" stage, how do we understand the causes and the nature of progressive recovery / healing in our reason, will, and emotion, considering that the *telos* of our redemption is to go back to the original design as exhibited in the perfect humanity of Jesus?** In other words, since the goal of God's redemptive work is to "Un-Fall" us, since we are *already* justified, and since the clarion call is to "imitate Jesus", wouldn't it make sense to expect *palpable* and *measurable* progress in our earthly experience of our reason, will, and emotion? If so, then naturally we seek to understand the *theological causes* and the *practices* that engender those effects. I would like a documented answer quoting a **21st century scholarly (published) work** of a Reformed theologian who **explicitly links** sanctification to *progressive restoration* in reason, will, and emotion, by describing how sanctification works toward the healing, in the Reformed tradition.
