I don't think it's being dramatic to say that this book changed you. I've been battling plenty of the passions that St. John mentions in the Ladder, that Fr. John so aptly applies to our everyday lives, simply but profoundly. He definitely writes as a co-struggler in the spiritual path. I found myself almost saying "Yes!" out loud, in agreement when he would comment on the things we do, or don't do, motivations and other things.
I tend to stay away from the actual Ladder, and deep theological writings like the Philokalia, the Evergetinos, St. Symeon the New Theologian's writings, etc. They are a little intimidating. But thank God that Fr. John has adapted this great work in simple terms, so that we could , at least in the most rudimentary sense, begin to apply it to our lives, and hope for the best.
Keep fighting the good fight!
