A few years ago, I read a book in which Proverbs 4:23 was used as the basis of protecting your heart. It goes,” keep thy heart with all diligence; for out of it are the issues of life”. The book was very insightful, illuminating the varying degrees by which Christians can be attacked. I must say though, when reading any Christian book, I always pray and ask the Lord to help me to discern if there is anything that does not line up with Scripture. At that time, I could not denote an issue with the book. I was so excited to have this newfound direction that I bought all the books pertaining to the subject along with workbooks with intentions on using them all.
