Law and Grace Called to share God's eternal life in Heaven but wounded by sin, Man stands in need of God's salvation. God's help comes to Man in Christ, whose teaching guides him and whose grace sustains him.
Law is a rule of conduct laid down by a competent authority for the sake of the common good.
The moral law is God's fatherly instruction that teaches Man the rules of conduct that will lead to the eternal happiness of Heaven. There are different expressions of the moral law - all of them interrelated. The natural law is the light of understanding given by God so that every human being can know what to do and what not to do. It is engraved in the heart and mind of every human being by the wisdom and goodness of God the Creator. Yes, the natural law does extend to every human being because it expresses the dignity of each person and determines the basis for each person's fundamental rights and duties.
