Hugh Martin is an author wider knowledge of whom, I think, would be helpful to the church in our time. Here is what I know he has written. I would welcome additions and links!
Jonah The Shadow of Calvary Christ for Us The Abiding Presence The Atonement (available from
Google Books)
Simon Peter
In addition a sermon or essay by him on Philippians 2:12,13 can be found in the back of Iain Murray's book
Pentecost Today
Does anyone know of anything else?
