In his epistle to the Romans, Paul gave this key to finding the peace promised by the Lord: "To be spiritually minded is life and peace." (Rom. 8:6.)
At the April 1991 general conference, Elder Joseph B. Wirthlin said: "In the scriptures, peace means either freedom from strife, contention, conflict, or war, or an inner calm and comfort born of the Spirit that is a gift of God to all of His children, an assurance and serenity within a person's heart. The dictionary definition states that peace is a state of tranquility or quiet, freedom from disquieting thoughts or emotions, and harmony in personal relations. (See Webster's Ninth New Collegiate Dictionary.)
"While we yearn for peace, we live in a world burdened with hunger, pain, anguish, loneliness, sickness, and sorrow," said Elder Wirthlin of the Quorum of the Twelve. "We see divorce with all of its attendant conflict and heartache, especially among the innocent children caught in the middle. Wayward, disobedient children cause their parents grief and anxiety. Financial problems cause distress and loss of self-respect. Some loved ones slip into sin and wickedness, forsake their covenants, and walk in their 'own way, and after the image of [their] own god.' (D&C 1:16.)
"The value of peace within our hearts cannot be measured. When we are at peace, we can be free of worry and fear, knowing that with the Lord's help we can do all that is expected or required of us. We can approach every day, every task, and every challenge with assurance and confidence in the outcome. . . .
"Few, if any, blessings from God are more valuable to our spiritual health than the reward of peace within. In modern-day revelation the Savior said, 'But learn that he who doeth the works of righteousness shall receive his reward, even peace in this world, and eternal life in the world to come.' (D&C 59:23.)
"Despite dismal conditions in the world and the personal challenges that come into every life, peace within can be a reality. We can be calm and serene regardless of the swirling turmoil all about us. Attaining harmony within ourselves depends upon our relationship with our Savior and Redeemer, Jesus Christ, and our willingness to emulate Him by living the principles He has given us."
