This is a fantastic book on friendship.
Full of great anecdotes, insights, wisdom, scripture, 90's references, and a look at the life and ministry of Jesus, this is a great book to help you grow as a friend.
Taking the idea of different types of friendship circles (often seen in Jesus as the 1, 3, 12, and 72 model), Knox synthesises it with some contemporary research, and gives loads of valuable encouragements and challenges for friendship.
