When I was in ministry, the problem I found with Bible studies was that I was simply trying to teach the Word (albeit from my slant), while many were simply trying to have what they already ‘knew’ confirmed in their own minds.
Others were constantly looking for something ‘new’ and became bored easily. Application fell on deaf ears, except for the few who were tenderhearted and truly seeking to serve God.
However, Bible studies on Revelation and ‘end times’ tend to be VERY popular. One preacher I knew up in Pa. has an ‘end-times’ Bible study every year to ‘bring in the crowd’. People who normally would be bored with a study of Romans or Ephesians, suddenly show up at the church door.
What in your estimation, is the reason behind the evangelical/fundamentalist obsession with Revelation and ‘end times’?
