One thing that is frustrating in such discussions is the false dilemma that is often presented:
1. Pastors need to be well equipped and adequately prepare that they might feed the congreation with the Word
or
2. People need to be attentive.
The answer is "Yes". Some are answering as if the Scriptures are completely silent on point 2 and get rankled when it is pointed out. This thread
is asking about how layfolk should react, Yes? I'm reminded of a scene in Full Metal Jacket where the D.I. yells at the man for leaving his locker unsecured and tells him that "...if it wasn't for idiots like you there wouldn't be any thieves."
It is not novel that we are to prepare our hearts for the hearing of the Word:
Q. 117. How is the sabbath or the Lord’s day to be sanctified?
A. The sabbath or Lord’s day is to be sanctified by an holy resting all the day,624 not only from such works as are at all times sinful, but even from such worldly employments and recreations as are on other days lawful;625 and making it our delight to spend the whole time (except so much of it as is to be taken up in works of necessity and mercy626) in the public and private exercises of God’s worship:627 and, to that end, we are to prepare our hearts, and with such foresight, diligence, and moderation, to dispose and seasonably dispatch our worldly business, that we may be the more free and fit for the duties of that day.628
The problem with the dialogue is that those who are pointing out that hearing needs to be conscientious are not denying that bad sermons exist but boredom is a state of mind. My reaction to bad sermons is typically not boredom but added concentration because, in some cases, I'm having to labor harder to ensure that I work through some of the dross and take things captive to the Word.
Like so many things, we can only be responsible for our own sin in a given context. If the Pastor has failed to do his diligence then we are not justified to forego our own responsibilities. Turning our minds off is not justified. It may be much easier to do and the poor preacher bears judgment for his inadequate feeding but we cannot righly condemn another for our own sin in any context.
Respondants need to stop putting premises into the presentations of others if they are talking about the responsibilities of one of the parties.
Thus, when a person notes that people should get plenty of rest before the Lord's Day so they aren't sleepy or that they pray and meditate on the Word in preparation for the Lord's Day, it's not "blame shifting" for bad preaching but simply noting each person's responsiblity to come prepared to Worship. Even the best preaching cannot fill in the gaps for personal sloth.
This discussion is odd because I cannot think of a single passage (nor has anyone offered any exegesis) that permits boredom in the House of the Lord.
