"When the nations that have no law, naturally do the things of the law, having no law, they are law unto themselves, and they show the work of the law, written in their hearts, their conscience at the same time testifying, and their thoughts blaming one another, or also apologizing." Romans 2. 14, 15
The highest Court of Human Justice is neither the Supreme Court of certain nations, nor the European Court of Human Rights in Strasbourg, nor the International Criminal Court, but my conscience!
Consciousness is an internal witness common to all human beings, whether they know the written law of God or not : this witness evaluates to excuse or accuse, approve or disapprove. By valuing certain good deeds and hating certain bad ones, men demonstrate an intuitive knowledge of the moral precepts of the Fa.
Consciousness acts alternately as a prosecutor and a defense lawyer. Of course, my conscience may be weak, and its inner testimony may be uncertain, confused, even erroneous. But I am best placed to know the facts and intentions that concern me.
Job examined himself in front of his friends who accused him of committing sins, as they supposed. No, he had not deceived his wife, he had not stolen money, he had not oppressed anyone ... His conscience did not blame him; she declared him just, innocent.
The Apostle Paul was accused at Corinth of all sorts of sins: baseness, greed, and so on. But his conscience did not blame him on these points. He could even be proud of the testimony of his conscience : "Our glory is this, to know the testimony of our conscience, that with simplicity and sincerity of God, not with carnal wisdom, but by the grace of God, we we are led into the world and more to you" (2 Corinthians 1: 12).
He considers his conscience as a witness, a prosecutor or a lawyer who gives their opinion ; he therefore listens attentively to it, but for him alone God has the authority to judge whether such thought or attitude is good or bad : "I have nothing on my conscience ; but by that I am not justified ; but whoever judges me is the Lord" (1 Corinthians 4: 4).
How important it is that our conscience keeps all its sensibility at all times, and that our Divine Master can always make us hear his voice !
