The title of the book is simply acknowledging that what God says in scripture and personal time with him matters, but what anyone else says about you doesn't matter anymore. It's not top priority--how I am looked at as a Christian, what has been done to me, or what has been said, even the unrighteous prayers prayed against me. I am in a good place heartwise, and my soul loves the Lord.
All of the testimonies written and experienced is enough to keep me until Jesus returns. Trusting that I may walk on this earth before and after salvation, that I have helped someone along the way in moving forward, staying humble when God uses this vessel to help someone grab hold of their salvation and all that God has for them.
