Prudence to the Naive

It IS possible to get prudence without experience. In our life of mine fields what would you give for the map out of that field? God has always given us the "map", but it's up to us to read and study it, to seek direction. We see that ignorance is no excuse and the consequences will come.
If the Bible has what it says it has, and we believe it, then why aren't we in it more and telling others?
