Marriage is a type and shadow of the true of mankind. And because it is temporal it is flawed but the image it testifies of is not flawed though. The real purpose is to reveal God's intention in mankind the whole mankind found in Christ. The real state of man; is Male and Female, one whole.

There is a good reason we don’t find it in the celestial hope we have in Christ. It is found though in the coming 1000 year reign of the King and His Kingdom. But not mentioned in the new heaven and earth.

The new heaven and the new earth has reference to more than just a place in the future. It speaks also of "the kind" that man is in designed as in the ORGINAL INTENTION. There is allot more to this but I won’t burden you with all my $0.02 any more than I have!
