William Barclay has written one of these commentaries for every New Testament book, that look at the whole of each book.
For Luke, William really brings it alive, with lots of information about the cultural aspects about some of the terms being used.
Often multiple possibilities are presented as to the message behind passages, with the authors favoured then being concluded at the end.
Luke is done very well, and this book has been really great as both a personal read (on the train, in bed etc) or as notes to assist with Sermon and service preparation.
William also does his own translation, which is great to compare to some of our modern day equivalents.
As with all Gospel translations and commentaries, use with wisdom. I didnt always find 100% agreement with every opinion, but hey he's only one of us humans...
I have now bought the whole series and am working my way throught them. The 2 volume on Matthews gospel is my favourite to date...
