I have about 177 chapters written in my book "The Hardshell Baptist Cult." Chapter 7 "Time Salvation - A Novel Idea" (see here) should be a must read for my Hardshell brethren. Let me cite some from the beginning of that chapter.
"Secrecy" of some sort is a characteristic of a cult. Christians have their "secrets" (Psa. 25:14; Prov. 3:32), but the distinctive secrets of the Hardshell cult are not the secrets of God or of His kingdom.
Basically, religious secrets involve "special revelation" that the cult, and it alone, possesses. Christians have "special revelation"; for instance, the knowledge of Christ as being the Son of God (Matt. 16:16, 17). But the claimed "special revelation" of the Hardshell is nothing but the blindness of a heresy.
Their primary "secret" revelation concerns the doctrine they call "Time Salvation." You have to be trained in Hardshell "dogma" to know all that the words convey. What the Hardshells believe the terminology, "Time Salvation," represents would never cross the average Bible reader's mind. You have to hear it from a Hardshell to be introduced to and informed in the meaning of its theological “jargon.”
I encourage all Hardshells to read this chapter.
