I generally notice a difference in myself when I'm meditating on God's word, and when I'm not. It's true that we're normally pondering something. I can easily get enmeshed and lost in my own thoughts, which sometimes go down a pathway that is not helpful or good.
As I take up a portion or passage in Scripture, I find over time as I ponder that grace begins to set in. God's love by the Spirit comes to the fore, and the old, doomed thoughts and attitudes are gone.
This is why I like to be in God's word all day as much as possible. God's word has a power all its own, and a wildness which can't be tamed, except by our systematic theologies, which can take the potency and power, yes what it really is as God's word, right out of it- and by themselves they do, as this excellent book which I'm rereading once again is reminding me.
How does God's word impact you? Or what would you like to share here?
