I think you are right, Wally...it is an internal issue. Our people should be at the place where they say, "If the Lord says it, I believe it", and they do it.... But sadly, that isn't the case.
I recently was asked to give a presentation on caffeine at a Methodist church. I gave a lecture and then used a slide presentation produced by Loma Linda, called "Caught in the Spiders Web". It is EXCELLENT! It is old, I don't know if they still sell it or not....(I hope so, cause the tape in mine broke at that meeting!) It is very interesting and convincing. They show what the equivalent of just 1 cup of coffee does to a spiders web, and how long it takes for it to be able to make a normal web again...
After the meeting, one of the women there said to the rest of the group, "Well ladies, now that we have learned this, what are we going to do about it? Are we going to continue serving coffee at our church functions?" I don't know what they ended up doing about that, but I do know that they were truly convicted. I had taken them samples of Dandy Blend, it is the best coffee substitute we have found, and they really liked it. And I made some carob fudge so they could try carob instead of chocolate...that went over real well. Education is a big part of helping people to turn away from things that are not healthy for them.... The Health Message truly is the Right Arm, the opening wedge, of the Gospel!
