L. TOM PERRY – Our strengthened family cultures will be a protection for our children from "the fiery darts of the adversary" (1 Nephi 15:24) embedded in their peer culture, the entertainment and celebrity cultures, the credit and entitlement cultures, and the Internet and media cultures to which they are constantly exposed.
