This is the world of the future, with inventions undreamed of that will come in your lifetime as they have in mine. How will you use these marvelous inventions? More to the point, how will you use them to further the work of the Lord?

…

From its beginnings, The Church of Jesus Christ of Latter-day Saints has used the power of the printed word to spread the message of the restored gospel throughout the world. The Lord, over the centuries, has had a hand in inspiring people to invent tools that facilitate the spreading of the gospel. The Church has adopted and embraced those tools, including print, broadcast media, and the Internet.

…

Now some of these tools—like any tool in an unpracticed or undisciplined hand—can be dangerous. The Internet can be used to proclaim the gospel of Jesus Christ and can just as easily be used to market the filth and sleaze of pornography. Computer applications like iTunes can be used to download uplifting and stirring music or the worst kind of antisocial lyrics full of profanity. Social networks on the Web can be used to expand healthy friendships as easily as they can be used by predators trying to trap the unwary. That is no different from how people choose to use television or movies or even a library. Satan is always quick to exploit the negative power of new inventions, to spoil and degrade, and to neutralize any effect for good. Make sure that the choices you make in the use of new media are choices that expand your mind, increase your opportunities, and feed your soul.

…

Now, may I ask that you join the conversation by participating on the Internet to share the gospel and to explain in simple and clear terms the message of the Restoration. Most of you already know that if you have access to the Internet you can start a blog in minutes and begin sharing what you know to be true. You can download videos from Church and other appropriate sites, including newsroom.lds.org, and send them to your friends. You can write to media sites on the Internet that report on the Church and voice your views as to the accuracy of the reports. This, of course, requires that you understand the basic principles of the gospel. It is essential that you are able to offer a clear and correct witness of gospel truths. It is also important that you and the people to whom you testify understand that you do not speak for the Church as a whole. You speak as one member—but you testify of the truths you have come to know.

…

As you participate in this conversation and utilize the tools of new media, remember who you are—Latter-day Saints. Remember, as the proverb states, that “a soft answer turneth away wrath: but grievous words stir up anger” (Proverbs 15:1). And remember that contention is of the devil (see 3 Nephi 11:29). There is no need to argue or contend with others regarding our beliefs. There is no need to become defensive or belligerent. Our position is solid; the Church is true. We simply need to have a conversation, as friends in the same room would have, always guided by the prompting of the Spirit and constantly remembering the Atonement of the Lord Jesus Christ, which reminds us of how precious are the children of our Father in Heaven.
