Many years ago my friend, Alex McManus, opened my eyes to the reality that, as Christ followers preaching the gospel, we're much like foreigners trying to speak a different language. 

For the most part you can tell a foreigner from a native speaker by the distinct accent that sets us apart. Alex opined that this makes us "Experiments in translation." We're interpreting an ancient text in a present context, and interpretation requires a colloquial, cultural, and context understanding. This means that we don't always get it right.
