Kindergarteners, Boy Scouts, police officers, doctors, lawyers and politicials do it. Why do we make oaths and enter into covenants? Life will eventually give you many reasons and excuses to break your promises. Oaths and covenants give you a divine reason not to break your promises even when life circumstances may seemingly justify it.
The selfishness, disobedience, obstinance, disloyalty and rebellion of mankind would give God every reason to allow mankind to destroy ourselves. But because of the covenant He has made with His prophets, and a few faithful of His people, He will keep His promises and preserve a remnant and eventually save and redeem mankind upon the Earth.
Here are a few oaths I made in my life:
Pledge of Allegiance:
I pledge allegiance to the flag of the United States of America, and to the republic for which it stands, one nation under God, indivisible, with liberty and justice for all.
Scout Oath, Boy Scouts of America:
On my honor, I will do my best;
To do my duty to God and my country and to obey the Scout Law; To help other people at all times; To keep myself physically strong, mentally awake and morally straight.

I solemnly pledge to consecrate my life to the service of humanity.
I will practice medicine with conscience and dignity.
The health and life of my patient will be my first consideration.
I will hold in confidence all that my patients confide to me.
I will maintain the honor and noble traditions of the medical profession.
I will give respect and gratitude to my deserving teachers.
My colleagues will be as my family
I will not permit personal considerations to interfere with my duty to my patients
I will maintain the upmost respect for human life.

These promises I make freely and upon my honor.
