Alma 48:11 - 48:15
Alma 48: 11 And Moroni was a strong and a mighty man; he was a man of a perfect understanding; yea, a man that did not delight in bloodshed; a man whose soul did joy in the liberty and the freedom of his country, and his brethren from bondage and slavery;
Moroni was what we would call a great man. He understood the real motives of men and how to counteract them. He did not enjoy warfare, but was willing to engage in it to keep his people free of domination from whose would deny them their freedoms.
Alma 48: 12 Yea, a man whose heart did swell with thanksgiving to his God, for the many privileges and blessings which he bestowed upon his people; a man who did labor exceedingly for the welfare and safety of his people.
He knew the source of his freedoms, namely God himself. He was thankful for the freedoms they enjoyed and delighted to see his people having the same freedoms. It was his mission to make sure they had them and worked tirelessly to help them keep them.
Alma 48: 13 Yea, and he was a man who was firm in the faith of Christ, and he had sworn with an oath to defend his people, his rights, and his country, and his religion, even to the loss of his blood.
He had a testimony of Jesus Christ. He also swore an oath to defend his people and to keep them free of evil domination and was willing to die to keep his oath.
Alma 48: 14 Now the Nephites were taught to defend themselves against their enemies, even to the shedding of blood if it were necessary; yea, and they were also taught never to give an offense, yea, and never to raise the sword except it were against an enemy, except it were to preserve their lives.
The Nephites had been educated to defend themselves against their enemies. They were not to be the first ones to start a fight, but if necessary, they were to finish it if it was started by an enemy.
Alma 48: 15 And this was their faith, that by so doing God would prosper them in the land, or in other words, if they were faithful in keeping the commandments of God that he would prosper them in the land; yea, warn them to flee, or to prepare for war, according to their danger;
This was an article of faith for the Nephites. If they would keep the commandments, they would be preserved from their enemies by being strengthened, or told to flee or prepare for war.
