“Many people try to find happiness and fulfillment in activities that are contrary to the Lord’s commandments. Ignoring God’s plan for them, they reject the only source of real happiness. They give in to the devil, who ‘seeketh that all men might be miserable like unto himself’ (2 Nephi 2:27). Eventually they learn the truth of Alma’s warning to his son Corianton: ‘Wickedness never was happiness’ (Alma 41:10). …
“As you seek to be happy, remember that the only way to real happiness is to live the gospel. You will find peaceful, eternal happiness as you strive to keep the commandments, pray for strength, repent of your sins, participate in wholesome activities, and give meaningful service. You will learn to have fun within the limits set by a loving Father in Heaven” (True to the Faith: A Gospel Reference [2004], 79–80).
“If we look to the world and follow its formulas for happiness, we will never know joy. The unrighteous may experience any number of emotions and sensations, but they will never experience joy! Joy is a gift for the faithful [see 2 Nephi 9:18]. It is the gift that comes from intentionally trying to live a righteous life, as taught by Jesus Christ [for examples, see 2 Nephi 27:30; Alma 27:16–18]” (Russell M. Nelson, “Joy and Spiritual Survival,” Ensign or Liahona, Nov. 2016, 84).
“God reveals to His prophets that there are moral absolutes. Sin will always be sin. Disobedience to the Lord’s commandments will always deprive us of His blessings. The world changes constantly and dramatically, but God, His commandments, and promised blessings do not change. They are immutable and unchanging. Men and women receive their agency as a gift from God, but their liberty and, in turn, their eternal happiness come from obedience to His laws. As Alma counseled his errant son Corianton, ‘Wickedness never was happiness’ (Alma 41:10)” (L. Tom Perry, “Obedience to Law Is Liberty,”Ensign or Liahona, May 2013, 88).
