The book is deeply encouraging. No matter what difficult situation you are facing, whether it is the result of someone else's sin or the result of your own, God is able to help, strengthen and empower us to bring about a good outcome.
Each chapter is complete in itself, though sometimes this creates a bit of overlap between chapters but this is only noticed if you read several chapters in one sitting. The advantage is each chapter can be studied separately. There is a study guide at the end to facilitate this.
An encouraging read.
