In this dispensation the Lord reiterated the commandment given at Sinai when He said, “Thou shalt not . . . commit adultery, . . . nor do anything like unto it” (D&C 59:6; emphasis added). From the beginning of time, the Lord has set a clear and unmistakable standard of sexual purity. It always has been, it is now, and it always will be the same. That standard is the law of chastity. It is the same for all—it is the same for men and women; it is the same for old and young; it is the same for rich and poor.
