So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth. The most precious thing you can give to another is your intimacy. Adultery kills the heart of the innocent spouse because something has been given to another which truly belongs to the spouse alone. Instinctively, each of us knows deep down inside that a person shows their deepest love by giving themselves to one and only one person in the world. Poeple have killed others due to this problem.
Intimacy is linked with real love.
One will keep themselves for the person they are to marry, and never allow anybody else to ever have it because this is one thing that is special above everything else. And to give it to any old person is rob someone of something special that nobody else should ever have. The one you really care about should receive something from you that nobody else will ever receive from you. That shows the person that they are needed. They are special above every other person.
