How is the Kingdom of God established in the world and in hearts? By going back to the Mosaic Law or by becoming acquainted with it if one is ignorant of it and, above all, by abiding by it absolutely, in every event and moment of our life. Which is that Law? Something so severe as to be impracticable? No. It is a set of ten holy easy precepts, which even a really morally good man feels he must respect, even if he lives in the most impervious forest of mysterious Africa. It says:
“I am the Lord Your God, you shall have no gods except Me.
You shall not utter the name of God in vain.
You shall keep the Sabbath according to the commandment of God and to the needs of the human body.
Honour your father and mother so that you may have a long life and be blessed both on the earth and in Heaven.
You shall not kill.
You shall not steal.
You shall not commit adultery.
You shall not bear false witness against your neighbour.
You shall not covet your neighbour’s wife.
You shall not covet your neighbour’s goods”.
Which good natured soul, contemplating what is around him, even if he is a savage, will not say: “All this was not formed by itself. Therefore there must be One, more powerful than nature and man himself, who made this”? And he worships the Powerful One Whose Most Holy Name he may or may not know, but he feels He must exist. And he has such reverence before Him, that when he utters the name which he has given Him or has been taught to utter to name Him, he trembles with respect and he feels that he prays when uttering it reverently. In fact it is a prayer to utter the Name of God with the intention of worshipping Him or making Him known to those who do not know Him.
Likewise, out of moral prudence alone every man feels that he must grant some rest to his limbs, so that they may resist as long as his life lasts. By deeper reason a man who knows the God of Israel, the Creator and Lord of the Universe, feels that he must consecrate his bodily rest to the Lord, so that he may not be like a beast of burden which rests, when tired, on litter crushing fodder with its strong teeth.
Blood also calls for love for those from whom we originate, as we can see in that colt that is now running braying towards its mother which is coming from the market. It was playing in the herd, it saw its mother, it remembers it was fed by her and licked with loving care, defended and warmed by its mother, and see? It rubs her neck with its tender nostrils and jumps joyfully rubbing its young crupper against the sides that carried it. It is a duty and a pleasure to love one’s parents. And there is no animal which does not love the mother which gave birth to it. What? Will man be more vile than worms living in mud?
A morally good man does not kill. He has a strong dislike of violence. He feels that it is not lawful to take anybody’s life, and that God only, Who gave it, has the right to take it. He abhors homicide.
Likewise, he who is morally sound does not take advantage of other people’s property. He prefers to eat plain bread with a clear conscience near a silvery fountain, rather than have a rich roast which is the fruit of a theft. He prefers to sleep on the ground with his head on a stone and friendly stars above him, pouring peace and comfort on his honest conscience, rather than toss about in a stolen bed.
And if he is morally sound, he is not eager for more women, who are not his, and he will not cowardly disgrace the nuptial bed of his neighbour. And he will consider his friend’s wife as a sister and will not cast lustful glances at her, as no one does at a sister.
A man with a righteous soul, even if only naturally righteous, with no other knowledge of Good but what comes to him from his honest conscience, will never take the liberty of giving false witness, as he would consider that the same as homicide and theft, which it is. But his lips are as honest as his heart, and his glances are honest, so he does not desire his neighbour’s wife. He does not crave for anything, as he knows that that is the first incentive to sin. And he is not envious. Because he is good. A good man is never envious. He is happy in his lot.
