Life is a journey. Each one is the “driver” of his own life. Still, we need the Law, directions to know which one is the right road, to know what is right and what is objectively wrong and would destroy us.
Thus, Law is not a limitation of choices, but the only place within which we can develop ourselves, and accomplish our purpose of existence, with God’s help.
For this purpose, God “inserted” in us the knowledge of Natural Law, limited but useful.
Furthermore, by revelation, God made known to us his Eternal law, which comes from God’s Wisdom. Together with it, God gives us the strength to fulfill it. All laws are derived from eternal law. No law is just if it does not conform to eternal law.
The Ten Commandments are a revealed expression of the natural law.
Civil law exists to embody the natural law in particular times and places for the good of those under it. These laws get their legitimacy by being grounded in the natural law.
What about unjust laws? ‘An unjust law is no law at all.’ Now, what is the difference between the two? How does one determine whether a law is just or unjust? A just law is a man-made code that squares with the moral law or the law of God. An unjust law is a code that is out of harmony with the moral law.
We are members of his body, which is the Church, and branches grafted onto the vine, which is Jesus Christ.
From then on, Christian life is a continuous conversion, also called “sanctification.” “Christian sanctity does not consist in being impeccable, but in fighting against and not yielding to temptation, in getting up again after a fall. It does not result so much from man’s will power, but rather from the effort of not setting obstacles to the action of grace in one’s soul. It consists in being humble cooperators of God’s grace.” This process of gradual growth in holiness culminates in everlasting life.
As Christians, “Our vocation is to follow Christ ... And to follow him so closely that we live with him, like the first Twelve; so close to him that we identify with him, that we live his Life, until a moment comes, if we haven't hindered it, when we can say with St Paul: It is now no longer I that live, but Christ lives in me."
