Elder D. Todd Christofferson
Using our agency to choose God’s will, and not slackening even when the going gets hard, will not make us God’s puppet; it will make us like Him. God gave us agency, and Jesus showed us how to use it so that we could eventually learn what They know, do what They do, and become what They are. (“Moral Agency,” 53)
Satan ... promotes conduct and choices that limit our freedom to choose by replacing the influence of the Holy Spirit with his own domination. Yielding to his temptations leads to a narrower and narrower range of choices until none remains and to addictions that leave us powerless to resist. (“Moral Agency,” Ensign, June 2009, 49)
