Even though Bible's revelation is progressive, both Old and New testaments are essential. Obscure passages are to be interpreted in the light clear passages. If you don't understand one reference pointed to by your concordance, go to another. Interpret experiences in the light of scripture, not scripture in the light of experience. The Beardsley's and Dave Wilkerson in particular.
Biblical examples are authoritative when followed by a command.
A biblical example can verify what you feel God is leading you to do. Biblical examples can be a rich source of application for your life. The believer is free to do anything that scripture does not forbid. It is acceptable to believe that Christians shouldn't do certain things, but you should ONLY use that to guide your own behavior. It should not be used to try to control the actions and conscience of another believer.
