Definitely expository preaching!
our sunday school (which follows the worship service) is a "small group" setting. The pastor has led it most of the time, but over the last couple of months he has asked me to lead, and I have. There is one man in the group who asks the most off the wall questions. It is a DISTRACTION to say the least. I want to open the Word, hear it explained, and hear it preached...I see a difference between explanation and having it preached: there is a sense of application and urgency with preaching.
I think small groups can be edifying...if it is led by one person where questions pertaining to that scripture are brought up: but that in no way should ever replace the preaching of the word on the Lord's Day. God has set apart preachers and teachers from the laymen. I don't care what Jack has to say about Scripture...i care about what God has said and what He says through his mouthpiece. While God might have dramatic things to say, the amazing thing is that this drama isn't exposed through acting: It's done through the plain explanation and proclamation of God's Word.
I may be misunderstanding what it meant by "dramatic" but I am picturing unneccessary posturing by a man who doesn't normally move in such a fashion. Part of the reason we joined the OPC in town is because another Reformed congregation in town has this preacher who focuses on oration. His hair is slicked back to the point his face looks like it's in pain, and his speach pattern is completely unnatural. I am not sure if he really is motivated by oration or if he's just an unnatural guy...but it comes off to me very badly and distracting. Man's foolishness is just that...God's wisdom is truly wise, though clowns may mock it as unwise.
