"A flesh-eating plague will destroy many. . . . Eaten up will be the tongues of those who scoffed and laughed at the warning of Armageddon! Eaten up will be the eyes of those who refused to see the sign of the "time of the end"! Eaten up will be the flesh of those who would not learn that the living and true God is named Jehovah! Eaten up while they stand on their feet!" (From Paradise Lost to Paradise Regained, 1958, p. 209)
That is dark.
No wonder I was "conflicted" as a young boy. Having very loving parents, and grandparents, but being taught this stuff at the same time...
