Joseph F. Smith
"I . . . stand upon this principle, that the truth is in the gospel of Jesus Christ, that the power of redemption, the power of peace, the power for good will, love, charity and forgiveness, and the power for fellowship with God, abides in the gospel of Jesus Christ and in obedience to it on the part of the people. I therefore admit, and not only admit but claim, that there is nothing greater on earth, nor in heaven, than the truth of God’s gospel which he has devised and restored for the salvation and the redemption of the world. And it is through that that peace will come to the children of men, and it will not come to the world in any other way” (Teachings of Presidents of the Church: Joseph F. Smith, p. 405).
