In the Bible, there are three great covenants: (1) the Jewish covenant given first to Abraham and defined by Moses, (2) the Christian covenant given to his straight disciples by Jesus, (3) the gay covenant given to us gay people by the prophet Isaiah some five hundred years before Jesus was born.In the Third Great Covenant, I discuss the three promises given to us and show how Jesus, son of God, was the supreme fulfilment of the gay covenant.
