In my posts on the introduction, I intended to put something in about the FCF: what Bryan Chapell labels, the "Fallen Condition Focus." Because it was a new concept to me (the term, "Fallen Condition Focus", not the fallenness of humanity!) I put off writing about including the FCF in the introduction and ended up not writing about it at all.
[The] FCF is a human problem or burden addressed by specific aspects of a scriptural text, informed preaching strives to unveil this purpose in order to explain each passage properly.
Colin has a longer quote and comment here. I recommend it.
