I have read In Conversation with God, too. I like it very much and have all the volumes but haven’t made much use of it in 3 or 4 years probably. I highly recommend it.
I might just continue with my book roulette. I have at least 100 great spiritual books on my shelf. Maybe the HS can just pick things out for me from day to day.
Lectio Divina is a practice I"d like to start doing- even if it is but from one verse in the Gospels each day.
