I get the point from the article - we've got to communicate and know our audience - however, shouldn't the goal of teaching the gospel to be to help define the terms of the gospel? For example, how can someone be saved without knowing what "saved" implies? Sin, salvation, forgiveness, eternity, heaven, hell, punishment are all terms that need to be taken into account if someone is going to understand why Jesus died. What purpose is a substitutionary death if the person doesn't know that sin carries a death penalty?

I agree witht he previous post. If a teacher doesn't teach his/her important terms, the student doesn't really know the subject. Teach the terms and the ignorance of the scriptures will disappear. However, when talking to a friends who knows nothing about the Bible, perhaps it would be wise to explain these terms with everyday language.
