The more people surrender to the fallen state of the human heart, the more the world gets pornographic. Sexuality becomes an idol, a fake connection that is sought in place of the Source. The natural energy involved becomes everything to the individual, a false fun that, like a drug, presents itself as the very reason to live. The whole world of men and women is tasted and it's still not enough.
How do you expect them to be faithful without the faith in something more?
Their hearts are cold and many without a doubt are "happy" that way.
