I've heard this described as "imputed righteousness", where God declares us righteous, and imparted righteousness, where God makes us righteous.Classically, the theologians differentiate between forensic righteousness (God’s judgment of us, concurrent with declaring us His people), and how well we meet our relational obligations at any point during the growing-up process which is classically called sanctification. It is this latter righteousness that sister Stunned by Grace longs for, if I understood correctly.
Much love!
