The Babylon book....I actually liked that one....it had some history that made it more than the usual pablum....then is finished the mystery of God one not so hot but okay...anyone remember that lime green Daniel book? But...that revelation book and its applications were pretty hard to digest. The conventions mentioned earlier....the one that got me was those dead bones fleshing up and coming to live...the imprisoned holy ones in WWI....get released and go apreachin......and yes.....repeat book study of it as nauseum...
I remember that creation book too.... Systematically skipping that book study because I couldn't stand that book.
