I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. Paul is not describing a pious theory here but a New Covenant reality: your old self was co-crucified. What lives now is Christ in you.
There are days when one sentence from the outside tips your inner world into self-accusation. But in Christ you are acquitted. Accusation has no right over you anymore, because the one who was accused has died. And the one who lives now is new.
Today you may live from this firm standing, even when old thoughts still get loud.
