 In February, 1992 Lampley sent out a letter declaring that he and Trescott would start on a five-week tour of seven western states to give testimony to their leaders in warning "that The Great Tribulation had begun on March 26, 1991 and that it would last for 1,260 days".Trescott later ended his association with Lampley and Anderson Fields Jr. took his place as one of the "two witnesses".Lampley was deeply affected by the 1993 burning of the Branch Davidian compound in Waco, Texas, keeping a framed photograph of the fire within his otherwise undecorated church which was set-up like a home office.
