Peter Adam points out that it is quite possible for a preacher to use the expository method and yet still remain stubbornly moralistic.

Thus (and I’m slightly paraphrasing here):-

• Genesis 1 – the importance of creativity
• Genesis 2 – caring for the environment
• Genesis 3 – none of us is perfect
• Genesis 4 – we must learn how to forgive

We need, says Adam, a Biblical theology as well as an expository method if we are to free our preaching from the dangers of mere moralism.
