You have plainly stated that it is Jesus obedience that makes God call a man righteous, not the mans trust.
I hardly know what to say.
God chooses to justify the ungodly when they believe Him, trusting Jesus, and He immerses us into Christ, into His obedient death. And through being immersed into Jesus in His death, burial, and resurrection, we are reborn, born from God, a new creation. This is our justification, that we are dead to who we were, the man of flesh born from Adam, and alive unto God in Christ. We are separated from our sins, completely and fully forgiven, and separated from the power of the flesh, and are no longer subject to sin's rule in our lives. We have been recreated sharing God's very own nature, righteous, and holy.
We are no longer in the line of Adam's humanity, but are a new humanity in Christ.
God gives us life to share with Him and to overcome the flesh and the world.
To say that our obedience, while required for the abundant life, and not to the Law, but obedience to Christ Himself personally, to say that this will determine our salvation at the end, that we are accepted or rejected based on whehter or not we've been obedience - and who is completely obedient? - is to live according to the the knowledge of good and evil, while Jesus came to give us life, abundant life.
Living according to the knowledge of good and evil, constantly judging, and if done honestly, self-condemning, because we all know when we disobey. Constantly wondering, never knowing, never resting.
Living according to life in Christ is liberty from labor, is to rest in Him, come to Me, and I will give you rest. He who has rested has ceased from his labors. To live according to the Spirit of Life, Who wells up with life inside us, to spill out from us, to shower all around us with blessing.
Much love!
