In his helpful little book the Priority of Preaching Christopher Ash provides 7 blessings of having consecutive expository preaching as the staple diet on the menu for the people of God.
1) Consecutive Expository Preaching Safeguards God's Agenda Against Being Hijacked by Ours.
In biblical ministry I want to exorcise three demons. "They are called Relevance, Entertainment, and Immediacy" (p. 111).
"To preach expositorily through a Bible book is to trust that the agenda of God is the right, the deepest, and the best agenda" (p. 112).
"That is not to say that we cultivate dreary preaching; it is to say that the content of our preaching is set not by the demands of entertainment, but by the agenda God has set in the books of the Bible."
2) Consecutive Expository Preaching Makes It Harder For Us to Abuse the Bible by Reading It Out of Context.
We often say that a text without a context is a pretext. You cannot just make the bible say whatever it is you want it to say and yet that is what many preachers do when they (often inadvertently) miss the point of the passage Sunday after Sunday.
"Consecutive Bible exposition helps us understand the Bible in its context and therefore understand it correctly, and not to abuse the Word of God by twisting it to mean something other than what God has made it mean" (p. 116). 2 Timothy 2:15.
3) Consecutive Expository Preaching Dilutes the Selectivity of the Preacher
