"Wo unto them that call evil good, and good evil, that put darkness for light, and light for darkness, that put bitter for sweet, and sweet for bitter!"

This is a verse that describes something very prevalent in our times. Where the commandments of God are tossed aside and we are living in a world were people are calling darkness light and light darkness. 

I see this from just the 10 commandments that every Christian believes in.

The Apostle L. Tom Perry spoke of this in This video:

In the video he says "In my judgment, four of the Ten Commandments are taken as seriously today as ever. As a culture, we disdain and condemn murder, stealing, and lying, and we still believe in the responsibility of children to their parents. 
But as a larger society, we routinely dismiss the other six commandments:
If worldly priorities are any indication, we certainly have "other gods" we put before the true God. We make idols of celebrities, of lifestyle, of wealth, and yes, sometimes even graven images or objects. 
We use the name of God in all kinds of profane ways, including our exclamations and our swearing.
We use the Sabbath day for our biggest games, our most serious recreation, our heaviest shopping, and virtually everything else but worship. 
We treat sexual relations outside marriage as a recreation, an entertainment. And coveting has become a far too common way of life." (Elder L. Tom Perry, "Obedience to Law is Liberty", April 2013, emphasis added)

I don't think anyone can deny the truths spoken of by this Apostle of the Lord, because these are things that we see in our everyday lives. In the media and television we see in almost every moment people who are trying to make evil things look desirable or even like it is something okay, or good.

It is necessary that we must be able to differentiate between the two.

For if we do our life will be sweet, as compared in the scripture.
