Symbols are a very powerful way to communicate a message. Symbols and parables often make known something that is not spelled out in words.
When I saw the LDS July 2015 New Era cover, a message was communicated to me. The Supreme Court’s landmark decision to make same-sex marriage an equal right set in motion “rainbow everything”.
To see the LDS temples portrayed in a rainbow theme, sends the message that LGBT marriages will soon have equal rights within the LDS temples.
