Genesis Chapter 12

The call of Abram, and the promise made to him. He sojourneth in Chanaan, and then by occasion of a famine, goeth down to Egypt.

The mind governs the entire person.

“Abraham represents the mind. In fact, Abraham signifies passage. Therefore, in order that the mind, which in Adam had allowed itself to run to pleasure and to bodily attractions, should turn toward the ideal form of virtue, a wise man has been proposed to us as an example to imitate. Actually Abraham in Hebrew signifies “father,” in the sense that the mind, with the authority, the judgment and the solicitude of a father, governs the entire person. This mind then was in Haran, that is, in caverns, subject to the different passions. For this reason, it is told, “Go from your country,” that is, from your body. From this land went forth the one whose homeland is in the heavens.” (4) -St. Ambrose

The just man completely puts his trust in God.

“The just man’s Godfearing qualities are demonstrated in the way he believed the words coming from God and accepted without demur everything, difficult though it seemed.” (4) -St. John Chrysostom

The Catechism of the Catholic Church states:

Man, tempted by the devil, let his trust in his Creator die in his heart and, abusing his freedom, disobeyed God’s command. This is what man’s first sin consisted of. All subsequent sin would be disobedience toward God and lack of trust in his goodness. (397)
