Conscience records the slightest tug at the understanding of love that we gradually grow into. "Don´t!" it says as soon as you violate the least of the commandments of love.
As people increasingly seek to live freely according to their desires - what the Bible calls "sowing in the flesh" - they try to find means and methods to avoid the consequences - what the Bible calls "to reap the destruction of the flesh" . But God says, "Don't get lost! God will not be mocked, for what a man sows, he will reap." Galatians 6, 7-8. They themselves will not avoid having to reap the destruction this brings upon humanity.
