 And we know it will end one day in the apocalypse. We've got to fill in the gaps in the meantime. But the time moves in one direction. Marriage here, in fact, the Christians raise it to a sacrament. Christ raises it to a sacrament. It says marriage is a symbol between Christ and his church. Christ the bridegroom, the church the bride. And it's a symbol of Christ's love for his church. So that marriage, from the Christian perspective, is permanent. And it moves in one direction.
