“...such obsessive preoccupation some have with trying to predict what the Bible tells us is NOT PREDICTABLE...”
Mormons and especially Jehovah’s Witness are notorious with obsessing over the book of Revelations. To the point they ignore all the other books in the Bible.
But of course, they are NOT Christian denominations.
Are you saying that they (Mormons and Jehovah's Witnesses) reject Jesus as Messiah and Savior?
