St. Paul, in the Bible, counsels the use of means other than “faith” for dealing with ailments...
“No longer drink only water, but use a little wine for the sake of your stomach and your frequent ailments.”
-1 Timothy 5:23
And yet, so many preachers preach adamantly that their people NOT spend a dime on good wine (I think it’s because it takes dollars out of their pockets).
Oh, and some preachers in the “name it and claim it” crowd also hold their parishioners in their control and demand that they just “have faith” and aren’t saved if they don’t do what the preacher says. So, the pressure is great for people to toe the line. I assume they think they’re truly doing the Lord’s work.
