got it for nursing school at UT Tyler. Love it as it's a great little resource to haul around everywhere which has a significant amount of great information which is needed for my classes and clinicals. Highly recommend it but due note that the 8th edition contains the same information merely a few pages are numbered differently and that older edition was nearly $30 less in price. Just an FYI if looking to save a few bucks...

Ordered new, got it used

Format: Paperback

Paid for a new book. It arrived very clearly used. It is in decent condition but it is frustrating paying that much for something to arrive used with damage.

Great Read

Format: Hardcover

Have always loved John Mark Comer's voice and tone as an author. He breaks down heavy and emotional concepts in an easy to read and understand way backed by scripture.
