You can’t have both.
Lusk: “Justification requires no transfer or imputation of anything. It does not force us to reify ‘righteousness’ into something that can be shuffled around in heavenly accounting books” (Richard Lusk, “A Response to ‘The Biblical Plan of Salvation'” in The Auburn Avenue Theology, Pros and Cons: Debating the Federal Vision: The Knox Theological Seminary Colloquium on the Federal Vision [Fort Lauderdale: Knox Theological Seminary, 2004], 142).
Now the HC, Q/A 60: “How are you right with God (i.e. justified/righteous)? Only by true faith in Jesus Christ…without any merit of mine, only by sheer grace, God grants and imputes to me the…righteousness…of Christ.”
I’ve bolded the key words under observation. These statements are completely at odds. One cannot honestly harmonize the two.
