I remember once my youngest son asked me why I had so many Bibles. I said so I could hear what God was saying better. He asked why I read it again, because I had read it so many times. Same answer, plus because His word is living. What is going on in my life makes me notice things in the word differently. He sat & thought about it and I read whatever it was I was reading and described why it meant more that day than when it did the year before.
