I like this series for "devotions", and this volume on Isaiah by John Ostwalt, is one of the best I've read so far in it. All this series provides the full NIV text to each "section", and covers, Original meaning, Bridge Context and Contempory Application. It isn't a verse by verse commentary and I would have preferred more detail in the exegesis, but it does give a very helpful "Broad Brush" approach to Isaiah without getting lost in minutia. As with most of this series it is Conservative Evangelical in Theology.
John Oswalt has also written the highly acclaimed 2 volume Commentary on Isaiah in the NICOT series, so he has much experience to draw on.
