Maybe I should have read the manual before I started.... nah! But it did get me thinking. We often plough straight ahead into situations that seem familiar, without consulting God or his word, because we think we know what we are doing. This is how Joshua came unglued at Ai; after the victory at Jericho he thought he was a pro, he thought he knew what to do.
I have found out many times, yet still need to remind myself, that however familiar I am with the word - I still need it on a regular basis. Daily is best (though I'm not religious, or superstitious about this). When I read God's word regularly, even when it doesn't seem directly applicable to my current situation, I do better in life than when I just try to cruise on my reserves. Reading God's word keeps us on track.
Jos 1: 8 Do not let this Book of the Law depart from your mouth; meditate on it day and night, so that you may be careful to do everything written in it. Then you will be prosperous and successful.
If you want some more on how important the word of God is to us, let me recommend Sue's Blog. Sue is a good woman of God, a member of Living Rock Church, and lives in Nuneaton (a great place to be!). She has just recently started Blogging, and is currently sharing on the importance of the word of God, based on her meditations on Psalm 119. Why don't you visit her site and give her some encouragement?
