Step-by-step explanation:
Because the morals demonstrated from the book help make us righteous in the face of the lord. We must have a heart and soul pure and cleansed so that we may have an impact on others who wish to seek the lord. The ten commandments were the rules god spoke into existence. Here is a principle spoken by god in a biblical verse: "Romans 13:8 Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law.
9 For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.
10 Love worketh no ill to his neighbour: therefore love is the fulfilling of the law."
