Faith is not trying to make something that is not already there happen. Faith is bringing out of the spirit realm what is already there, what is already true of you. Not to confess something that you are not. Whether you confess that you are the righteousness of God in Christ or not, you are still the righteousness of God in Christ. But when you confess it, you become conscious of it. You sense it, and it becomes powerful and real in your life.
You do not confess that you are righteous in order to become righteous. You confess that you are righteous because you are already righteous! Similarly, you confess that you are rich not to become rich. You confess that you are rich because you are already rich through Jesus. At the cross, He became poor so that you through His poverty might become rich! You confess this to be conscious that through Jesus, you are already rich. That's not having faith in faith. It is faith in His goodness, in His grace.
