I'm reading my first book by Steven Runge (Romans) and am learning so much. I looked on Logos and then online to see if he had anything out on Ephesians which I am studying with my church. I found a listing on Best Commentaries that showed an Ephesians version published in 2018 but was not able to find anything else about it or one that is sold anywhere. Seems like it was never published. I did find a YouTube of his on Ephesians 1 and wow, such great information. I hope a volume on Ephesians does get published. Paul seems to get so distracted in Ephesians, like his prayer gets broken up in 3 sections with so much powerful teaching in between.
