This promise helps Cub Scouts develop a sense of spiritual awareness, loyalty, unselfishness, self-discipline, and service to others.

On my honor: Saying "On my honor" is like saying "I promise." It means that you will do your best to do what the Scout Oath says. 

To do my duty to God and my Country and Obey the Scout Law: A duty is something you are expected to do. You do your duty to God by following the teachings of your family and religious leaders. You do your duty to your country by being a good citizen and obeying the law. You promise to live by the 12 points of the Scout Law. 

To help other people at all times: Many people nee help. A friendly smile and a helping hand make life easier for others. By helping other people, you are doing a Good Turn and making our world a better place.

To keep myself physically strong, mentally awake, and morally straight: The last part of the Scout Oath is about taking care of yourself. You stay physically strong when you eat the right foods and get plenty of exercise. You stay mentally awake when you work hard in school, learn all you can, and ask questions. You stay morally straight when you do the right thing and live your life with honesty.
