repent of those things

David O. McKay: The message of these young men who are going in all parts of the world, the message of the Church to all the world is: Repent of those things which contribute to the superiority of the physical senses over our love for spirituality. That is why they cry repentance! What does repentance mean? A change of life, a change of thought, a change of action. If you have been angry and hateful, change that hatred and enmity to love and consideration. If you have cheated a brother, let your conscience smite you and change that, and ask his forgiveness, and never do it again. In thus changing your life from those things which are on the animal plane, you repent of your sins. If you profane Deity, never do it again! Instead of profaning his name, worship him! And once that feeling of change comes to the soul, you desire to be born again, to have a new life. . . .This changing of life, this repenting is what the world needs. It is a change of heart. Men must change their way of thinking! Change their way of feeling! Instead of hating and fighting and crushing one another, they should learn to love!
