Don Carson's "For the Love of God" vol. 1,
has got to be the best devotional book I have ever read.
It follows the Robert McCheyne reading plan, which means reading 4 chapters a day, so that in a year you read through the Whole Bible once, and the Psalms and New Testament twice.
Each day, Carson writes something on one of the readings, and will often tie it into God's plan of redemption.
What makes this devotional book so different to most, is that the comments are not on verses taken out of context.
Furthermore, you are getting comments by probably a first rate scholar, so its a lot more reliable than your average devotional.
I'd thoroughly recommend it, if anyone is looking for a new reading plan, or devotional for 2008.
Peace
D
