Some good advice here: before you preach a book of the Bible, try to live “inside” it first.
In line with the way one ought to prepare to preach any book of the Bible, the preacher needs to live inside a Gospel for a while before trying to preach any part of it. Reading it through at a single setting, several times, is a great way to begin; for those who have the training, working carefully through the text in Greek during preceding months will prove personally rewarding and homiletically enriching.

So far the above collection of essays is well-written and helpful. I’ll post more about it in the coming weeks and months.
