The Problem of Fervor

Evangelicalism often measures sanctification/spiritual maturity/holiness by fervor.

This is wrong.

In the Bible and the majority of the Christian tradition, sanctification is measured by how I live and what I do. Do I love my wife as Christ loved the Church? Am I generous with my money? Do I love my children? Do I attend to the public worship of the Church on the Lord's day?

It's how you live.
