But what exactly is the “Righteousness that comes from God?” Is it a forensic righteousness that is not our own but is given to us by an act of God? Is it righteousness that we have access to by faith but we don’t really have until we, as you say, participate in and own it?
Man wasn’t created to be a sinner, but on his own, left fully in the hands of his own counsel he
will sin if he’s departed from God. Adam was given that choice-to obey or not-and off he went. So man’s ultimate justice or righteousness is intrinsically connected to and dependent on his relationship with God. He falls from the noble being he was created as to a
much lesser being to one degree or another when he’s not in union with Him. So God’s righteousness is a foreign righteousness only because
God became foreign to man-while man thought he was fine with his own “righteousness”, determining morality for himself, being his own god effectively. But while man has the freedom to make such a determination, he doesn’t have the
right to do so-only God does. Man’s righteousness is
nothing, nothing but moral relativism really, doing what’s right in his own eyes as it were.
God’s righteousness is a free gift, of Himself, of His own righteousness, primarily love. We receive it in seedling form at justification but it’s meant to be grown, with more expected back from those given more in terms of whatever: time, opportunity, intelligence, maturity, experience, revelation/knowledge, grace. We love because He first loved us-and that love is the most valuable and powerful and beneficial thing in the universe. But we prefer ourselves, we prefer pride to love; we trample all over love, over God. Man prefers darkness to light. Getting tired now. Long day. Old man.
