In 1978, Southwest Radio Church published a pamphlet entitled God's Timetable for the 1980s in which were listed prophecies for each year of the 1980s, culminating with Christ's return and the establishment of his millennial kingdom on earth in 1989.
In a 1979 book, Is This the Last Century? (Thomas Nelson) Webber and Hutchings again explicitly suggested "that the Tribulation will begin in 1981, that Christ will return in 1988" and that the "seven years from 1981 to 1988 will be the Tribulation period." .
