It's easy to relate to John Grimes, especially as I grew up in church myself. I had many doubts, like John, with sexuality and spirituality. 
It has a very unique way of telling the story, with different POVs that kind of come together at the end. You get the feeling that everything makes sense now, and you understand why the characters behave the way they do. The fact that everything in this book takes place in one day, is also insane. We get some throwbacks and such, but technically everything happens on that one Saturday in March. 
This was an emotional read, so powerful and great. I understand why Baldwins work is praised and loved by many. I will definitely read more books by him.
