1. It depends on whether your version (or level) of Logos included this commentary series. If it does, then it depends on when you purchased it. If it doesn't, but you purchased this series as an add-on, then it depends on when you purchased the NICOT/NT series. This particular commentary on 1st Corinthians is the revised edition of the original 1987 version: this one was published in 2014. If you purchased your Logos software or the NICOT/NT series prior to, or surrounding the time of its publishing, then you wouldn't have this, and it would need to be purchased independently of what you already purchased.
