I picked this book just after reading the Diary of Sr Faustina. And I find many similarities in the messages. I think these are personal revelations with the message to the author to go and evangelize. If the mission is to draw all to Christ, the Eucharist, the respect to His mother and the sacraments is fulfilled I guess the author is doing their mission by writing the book. What I've learned is that in every message from the angel or even from God; - the message is trust in God, love Him, read His word and stay holy. -Draw close to the father -Reject Satan because the world is slowly unraveling (quite quickly right now I might add) - Rejoice always in God -God can do everything but He wants us to love Him -He is an ever present Father -He wants us to be at peace. Love joy peace... that's pretty consistent in all the messages. And no matter what your past, His mercy is bottomless.
I really doubt whether her experiences were divine at all. Guardian angel Daniel talking to her and meeting Jesus and God? Give me a break. There has to be some good explanation for this kind of experiences because I believe the devil has many good tricks up his sleeve.
