So, you agree it teaches that a Christian who does not walk by faith is sinning and is not justified but "condemned".
Good.
So, again:
1. How do you square your understanding of Ro 8:1 with Ro 14:23? I've already provided my answer--one which is, to me, satisfactory and holistic.
2. On what grounds could you object to the simple and straightforward reading James 2 as teaching this selfsame thing--that your ongoing justification can be affected by your deeds, and that you must not only have faith but also walk in faith?
