And too bad some people fill it with sex? What is she talking about? The Baha'i God supposedly design people to have sex and to want sex. But then puts all kinds of restrictions on who, where, and when to have sex? Knowing that most all people aren't going to be able to obey this God's restrictions?
People CAN wait till they get married to have sex, most people just don't want to, but God is not going to lower His standards for those people.
If most people are not able to wait till they get married, that's their problem, and it is only a problem if they are Baha'is, since nobody else is held to this standard.
God didn't have to make sex so desirable (As if he did). Very easily it could just be how natural instincts work. He or she looks good. It feels good. Go do it. Then religious leaders say, "Wait, God says no. Gotta get married first. Don't do it and don't even think about it, until you're married." Then how many religious leaders get caught doing it.
Why does God make sex so desirable? Well, primarily to guarantee continuation of the human species.
But there is another reason. It is because God wants us to struggle and rise above out our natural instincts.
An old friend of mine who was the owner of the Planet Baha'i forum once posted this and he gave me permission to post it:
"God is calling us to struggle against our lower nature and to become who we truly are: not material beings, not sexual beings, but
spiritual beings who are in control of the physical side of our nature and who can thus find true happiness living in conformity with His will. Although not scriptural, there is a possible explanation of why He has made it so hard that I ran across long ago in a Baha'i children's book: Because if it were too easy, it wouldn't be worth anything. Or put another way, because only by being challenged can we really prove our love for God."
