I have joined a Faithlife group: https://faithlife.com/ot-quotes-in-nt
I am excited about the potential of the Faithlife groups, however there doesn't seem to be much activity. I would love to be in some groups that are as active as the Logos forums. So if you have any interest in the NT use of the OT, I would encourage you to join the group and contribute to the discussion.
Also, I would love to know about any groups that you are a part of that are active.
