If you are struggling to find your people within Christian community - this book is ABSOLUTELY for you! I personally purchased this study to provide guidance and insight on building Christian community as I start to develop a single's ministry at my church. It helped in some ways for that, but as I was reading it it reminded me of where I was a year ago - super active in my mega church, attending all the extra events and bible studies, praying desperately for God to being Christian friends in my life that I connected with (preferably in the same season of life as me), and not making any lasting or meaningful connections. That went on for 4 years and then all of the sudden God brought my people together and I growing deep roots in my Christian community.
I would also really recommend this for teenagers/young adults and their parents. These are the ages we have a lot of changes in our lives socially and friendships are a huge part of that. This book addresses the differences between Christian friends and other friends and the necessity for each in God's plans for our lives and our relationships. It would be a great way to prepare or walk thru those situations as you navigate some of those relationships in your life.
