Because our daughter studies ballet, one of the pieces of music that I'm frequently fixated on is the Nutcracker Suite by Pyotr Ilyich Tchaikovsky. Lauren has been in multiple productions of the Nutcracker ballet, (as have Deborah and I!) I've heard the music over and over. I know it really well. It probably borders on obsessive/compulsive behavior, but during the Christmas season, I listen and re-listen to it so many times that I get to where I "hear" it all day, even when it's not actually playing! And I should point out, I'm not complaining about this. I really don't get bored with it. In fact, whenever I'm on one of these musical "kicks" I find that no matter how many times as I listen to a piece of music, it isn't uncommon to continue picking up new nuances in the music that I hadn't really noticed before. And for me, that's really enjoyable!
I think this is the sort of thing that the psalmist has in mind in Psalm 119:97 when talking about meditating "all day long". This entire psalm, (which, by the way, is a fantastic work of Hebrew poetry!) centers largely on God's Word. The psalmist uses a variety of words to describe Scripture: word; commandment; statutes; way; precepts; law. But through it all is an overriding theme of having a real delight in the Bible, and repeatedly the idea of meditation surfaces. The word meditate means to "engage in contemplation"; to ponder; to muse; to think. And the author of Psalm 119 is saying here in verse 97 that he engages in this sort of thought about God's Word all day long. He's fixated on it. He is "hearing" it even when he has stopped reading it. He is picking up nuance that he hadn't picked up before. And while some might even consider it obsessive/compulsive, he finds more and more that he loves it!
Are you regularly meditating on God's Word? Are you consuming it in such a way that it stays with you all day? Pick a passage, however long or short, and get fixated on it for a while. Get to the point that it sticks with you all day long, and watch what happens. You will likely find yourself echoing the author of this great psalm in saying "Oh, how I love your law!".
