This will vary a bit depending on whether parents are issuing the invitation or whether the couple are doing so but in general this style is acceptable:
"If not for Love, world would have been extinct long ago" _ Even if the whole world is being computerized, people aren't computerized; they are still the same as they were ages ago. People love to love and to be loved. Weddings are the ultimate step after love; since people like you and I want the best of everything we prefer the best when it comes to our wedding. Is it enough if our would_be alone is perfect?? Certainly no. We want the paramount stuff in anything and everything, be it the wedding cards, bouquets, cakes, dress, stationary etc; we don't compromise for anything but the best.
