scared kinda i don't know if anyone reads this

tonight is the second week our journey team has been in the "crazy love" study from the book by the same name by francis chan - that's him in the photo in case you were wondering who is that? i have really gotten in to the book, but tonight we hit chapter 4 titled "lukewarm" and it kinda scares me or maybe better put as making me uncomfortable. francis gets a bit in your face with some probing thoughts and questions. main question for me is a look inside myself and what is my temperature for God? it kinda scares me.... am i lukewarm? doesn't this incredible God deserve more than i am willing to give? i gotta look in the mirror and say truthfully, where am i in my relationship with God? is it just the stuff he gives me that measures my love for Him? what does it look like to be sold-out to Him?
i don't know if anyone reads this blog, but if you are reading this i encourage you to read this book. it will evoke inward thoughts and discussions about ourselves that we need to be asking. at the end of chapter 3 chan writes, "our love for Him always comes out of His love for us". so the real deal is do i really know and love God?
