"let us hear the conclusion of the whole matter . fear God , and keep his commandment : for this is the whole duty of humanity " Ecclesiastes 12:13
God created us in his own image , and as such there are responsibilities God want us to perform ; that is to say those responsibilities are our duties on earth . your "whole duty "is to keep the commandments and the precepts of God . our duty as human beings is to obey in all things , the word of God .

that is the reason for judgement , God will judge the world primarily because , they refuse to perform their God given responsibilities . Adam and Eve were created and put in a furnished garden [Eden ], where there was anything edible . But GOD gave them one duty , that is ; a commandment not to eat the forbidden fruit .

But they didn't obey the commandment , that is because there was no fear of God in their heart .The word of God has been given to us to know the will of God for our lives . the will of God is how God would like you to live your life on earth . the word of GOD HAS BEEN GIVEN TO US to know our duties on earth. hebrews 10:7 declares "then said I , lo I come in the volume of the book it is written of me ] to do thy will , O God "

the book here is the bible , the holy scriptures , in it are written volumes of words about you which is the will of God for your life . that is the more reason why the child of God has to pay attention to the word of God.

"the Law of the Lord is perfect , converting the soul ;the testimony of the Lord is sure , making wise the simple .

the statutes of the Lord are right , rejoicing the heart ;the
commandment of the Lord is pure , enlightening the eyes . the fear of the Lord is clean , enduring forever : the judgement s of the lord are true and righteous altogether " psalm 19:7-9

when we as Christians identify with our God given duty and perform them , then we Will;l be rewarded as faithful children of God who did what was expected of them . DESIRE TO KNOW YOUR DUTY ON EARTH . and perform your responsibilities "for GOD SHALL BRING EVERY WORK INTO JUDGEMENT , WITH EVERY SECRET THING , WHETHER IT BE good OR WHETHER IT BE EVIL. ECCLESIASTES 12:14
