Do you agree with what it means though? Do you agree that we have nothing to give to God or do in order to receive righteousness from Him because we are sinful? So that makes it a passive righteousness.
There is no other righteousness. It's a redundant statement to call it passive.
God's righteousness, imputed to me by grace, is not passive on God's part. Once, God imparts his righteousness upon us, it becomes active in sanctifying us.
What you are conveying is grace. God's unmerited favor given to us without any need for us to accept or reject his favor. God simply chooses to impute his righteousness upon us and we respond with "Abba Father."
What I don't understand is how anyone could balk at such grace and complain that they weren't given the opportunity to choose whether they accept it or reject it. Who would say, "God you're a cruel task master for making me righteous and white as snow. I really, really wanted to remain depraved and in slavery to sin."? I can't imagine anyone being that foolish, yet we have people arguing for that choice here on the CH. It is a level of disrespect that I am thankful God does not hold against them as they rail away in their ignorance. I was once a free-will proponent. I understand how hard that delusion works to deny God His position of supremacy in our lives. God worked with me for decades before I saw my error.
There is only righteousness (God's perfection) and corruptness (human failure). The term "passive" is redundant.
