" Marriage is not a human invention; it is a divine revelation. Its design never was our own made-up arrangement of infinite malleability. It was given to us, at the beginning of all things, as a brightly shining fixity of eternal significance. We might not always live up to its true grandeur. None of us does so perfectly. But we have no right to redefine it, and we have every reason to revere it. "
― Raymond C. Ortlund Jr. , Marriage and the Mystery of the Gospel (Short Studies in Biblical Theology)
