Does Anyone Memorize Scripture?

This winter I had the opportunity to attend a quizzing competition at Bayview Glen church in Toronto. Groups of youth from across Ontario were particpating in a contest to see who had done the best job of memorizing an entire book of the bible. I was amazed with the discipline it must have taken for them to learn what they knew. I was amazed with the mental gymnastics they seemed to go through to recall what had been enscribed in their brains. But most of all I was amazed with the impact I knew it would have throughout their lives because they could not possibly have meditated on the scriptures that long without taking some of their meaning to heart. I immediately tried to recall a portion of scripture that I had memorized about 20 years ago when I first became a Christian and I was completely surprised to find that I still remembered most of it! I've started working on it again and I find it to be a very engaging way to meditate on God's Word when I have a quiet moment throughout the day. I was just wondering if anyone else has memorized scripture or if anyone else would like to try it. Maybe we could quiz one another and have some fun while learning more from God's Word.
