It is because in the bible it said that the lord would come back. We are in the end times as we all know it . NASA is afraid to admit that there is an actual meteor heading towards earth. The reason for this is because everyone will freak out . Only the rich and powerful can save themseleves. My dad works in NASA and this is what he told me and my mom.
Mastery of bible alone preaching is not always telling the TRUTH, sometimes they mixed with horrible lies that comes from their heart, and to those people who are enlighten with "sola scriptura" bible alone preachers, are being brainwashed. Most people are not even knowing this but they feel it instead.
The bible is a collection of mythological texts written by a group of ignorant Bronze Age nomads. It is rife with scientific and historical errors, contradictions, and questionable ethics. There is no "truth" to be found there, whether its preachers are teaching sola scriptura or not. Though the ones that preach "bible alone" are certainly exposing the nonsensical nature of their texts clearly for all to see. The rise of such fundmentalism coincided with a sharp rise in non-religious population of Americans for a reason.
