"Plans fail for lack of counsel", - Proverbs 15:22 http://www.biblegateway.com/passage/?search=Proverbs15:22&version=NIV
"What could be difficult or complicated about running? You just lace up your shoes and take off!
That's how many people think, and to a certain extent it is true. ... But, that doesn't mean it is easy, especially when longer distances are involved. So getting advice from experts and experienced runners only makes sense. They can give insight and guidance in every aspect of running, from choosing the right shoes to knowledge of training programs and plans....
Some believers have the same simplistic approach to their relationship with God... so they may try running the Christian race on their own, with no outside input or help. In doing so, however, they may be unprepared for what lies in their path, or they may take a wrong turn. The bible offers several encouragements to listen and learn from others, as well as warnings about false teachers who will try to lead us astray."
