We tend to use v105 as a text for talks on guidance. The problem is for the most part that the Bible doesn't help us with our guidance...it helps us with the simple decisions: 'should i kill my neighbour?' but most of the decisions in daily life the Bible does not actually make for us. And we should not pretend it does. But what the Bible does do is to light our feet so that we do not stumble into wrong.
Christopher Ash, Bible Delight, P 141.
I've often wondered if we think life would be easier if our Bibles were like the wands in Harry Potter. When the times comes we go to the shopkeeper, he asks us some questions, does some tests and then gives us the right Bible for us. The right verses to help us with our specific struggles, some individual advice on careers, marriage, education etc. But it's not like that. So Ash again:
So it is no careers guidance, but a light to keep me walking in the right way. To protect me from the traps of darkness and from falling into sin. When the devil tempted the Lord Jesus, it was the word of God that was a light to his feet.
