Imminence is a moment by moment thing. It’s like “you had better be ready ‘cause you don’t know when the master of the house is coming home”. All eschatologist get paid to read signs of the time. Some get paid for “now”, some get paid for “not now”. The “nows” make money off the “not nows” and the “not nows” make money off the “nows”. Gauranteed, if we were transformed according to our eschatological theories, all would be pre-trib.
Then why do the date-setting "Jesus is absolutely gonna return to this generation” crowd make it seem that “imminence” is the sole domain of futurist, literalist dispensationalists? And unless you believe with all your heart, soul, mind, and strength that Jesus is gonna return before you finish your cup of coffee you really do not understand imminence?
People who make a profession out of reading the signs of the times often go by another title, "false prophets".
