The reason why this book is entitled All For God is that Author Shawn Yurina   Richardson wrote it when he was compelled within his spirit to do so in jail. 

The Apostle Paul was in jail, and he wrote the majority of the New Testament. John the Baptist baptized many people in the river, but he wrote letters and sent messages to others during an isolated time of his life. Joseph was given authority over everything that belonged to the king, but before the king delegated that authority to Joseph, there was something that happened to him when he was incarcerated. There is something that these men have experienced that this author can relate to. There is a powerful anointing that this prophet has been able to produce, which compelled him to seek God through prayer-giving God his ALL. This book of prayer was produced when he was incarcerated. It will help bring you into the mind of Christ.
