You know that I have served your father with all my strength, yet your father has cheated me and changed my wages ten times. But God did not permit him to harm me.
Whether you are a child of God or not, some facts still remain unchanged. For example, you reap what you sow. Jacob cheated his own brother, later his own uncle cheated him. The measure you mete out to others, the same measure will be meted out to you.
