The January kingdom ministry has two study articles and the the whole insert - all about how the What Does the Bible Really Teach is now the number 1 teach aid - no longer the Knowledge book. In fact the instructions in one of the SM items is to switch to the Teach book as soon as possible with our bible studies. It will be the offer in March and of course is being studied in book groups after the Daniel book. The 2nd book will still be Worship the Only True God book.
The Knowldege book has had a short life indeed.
