The statistics part of the program was in Leon Weaver's talk.
What is interesting about the downward trend in bible studies is that effective January, 2015, the first Saturday is no longer Bible Study day. So, go figure.
I've seen lots of bible studies come to the hall. They come for awhile, then they go. In the last ten years, several were baptized. One quit attending almost immediately. Another one who attended quite regularly at first now attends very sporadically. Another family attends, but the husband was raised "around the truth", so there's the advantage there. I've seen plenty of other studies come for awhile and then disappear.
What's my point? Bible studies is NOT a good measure. How many of those bible students get baptized should be the real measure. There is no record in the Bible of anyone conducting a bible study with anyone else. Yes, there were those who would explain the scriptures for a few hours, but that doesn't count as a bible study. What counted was that the person was baptized.
