Doctrine and Covenants 63: 58-64

 

How are we treating sacred things with reverence?

"58 For this is a day of warning, and not a day of many words. For I, the Lord, am not to be mocked in the last days.

59 Behold, I am from above, and my power lieth beneath. I am over all, and in all, and through all, and search all things, and the day cometh that all things shall be subject unto me.

60 Behold, I am Alpha and Omega, even Jesus Christ.

61 Wherefore, let all men beware how they take my name in their lips—

62 For behold, verily I say, that many there be who are under this condemnation, who use the name of the Lord, and use it in vain, having not authority.

63 Wherefore, let the church repent of their sins, and I, the Lord, will own them; otherwise they shall be cut off.

64 Remember that that which cometh from above is sacred, and must be spoken with care, and by constraint of the Spirit; and in this there is no condemnation, and ye receive the Spirit through prayer; wherefore, without this there remaineth condemnation." (Doctrine and Covenants 63: 58-64)

And here's the commentary entitled: "Sacred things should be treated with reverence."

"The principles in Doctrine and Covenants 63:58–64 go beyond taking the Lord’s name in vain. What other sacred things come “from above,” or from God? What does it mean for you to speak of these things “with care”?"

Other sacred things that come "from above" or from God are: human beings or ourselves (children of God), the words in the scriptures, the earth and everything on it which God created, and many man-made things like temples, meetinghouses, books, and a lot of things. To speak of these things "with care" means showing deep respect as we talk about them. 

God has entrusted each of us with our minds and our physical bodies and so He wants us to treat ourselves with reverence. As we choose to do so, it's easier to treat everything else that God entrusted us with reverence as well.
