The following are excerpts from Elder D. Todd Christofferson’s talk on Moral Agency… (I highly recommend you read the entire talk)

…after the existence of choices and a knowledge of choices, is the next element of agency: the freedom to make choices. This freedom to act for ourselves in choosing among the alternatives that the [natural] law establishes is often referred to in the scriptures as agency itself. For this freedom we are indebted to God. It is His gift to us…

Let us pause and note that freedom of choice is the freedom to obey or disobey existing [natural] laws — not the freedom to alter their consequences. Law, as mentioned earlier, exists as a foundational element of moral agency with fixed outcomes that do not vary according to our opinions or preferences.

We recognize the gift of agency as a central aspect of the plan of salvation proposed by the Father in the great premortal council, and that “there was war in heaven” to defend and preserve it.

And ye shall know the truth, and the truth shall make you free.

So, being Jesus’ obedient disciple—just as He is the Father’s obedient disciple—leads to truth and freedom. Then He added, “If the Son therefore shall make you free, ye shall be free indeed.”

…the Lord’s statement that the truth will make us free has broader significance. “Truth,” He tells us, “is knowledge of things as they are, and as they were, and as they are to come.” Possession of this knowledge of things past, present, and future is a critical element of God’s glory: “The glory of God is intelligence, or, in other words, light and truth.” Does anyone doubt that, as a consequence of possessing all light and truth, God possesses ultimate freedom to be and to do?
