"For verily, verily I say unto you, he that hath the spirit of contention is not of me, but is of the devil, who is the father of contention, and he stirreth up the hearts of men to contend with anger, one with another." (3 Nephi 11:29)
"But, behold, the judgments of God will overtake the wicked; and it is by the wicked that the wicked are punished; for it is the wicked that stir up the hearts of the children of men unto bloodshed." (Mormon 4:5)
"And it shall come to pass among the wicked, that every man that will not take his sword against his neighbor must needs flee unto Zion for safety." (D&C 45:68)
"Yea, and this is not all; I command you by all the desires which ye have for life, that ye deliver up your weapons of war unto us, and we will seek not your blood, but we will spare your lives, if ye will go your way and come not again to war against us." (Captain Moroni, Alma 44:6)
"But behold I say unto you, love your enemies, bless them that curse you, do good to them that hate you, and pray for them who despitefully use you and persecute you; That ye may be the children of your Father who is in heaven; for he maketh his sun to rise on the evil and on the good." (3 Nephi 12:44-45)
God fights the battles of Jehoshaphat
"It came to pass after this also, that the children of Moab, and the children of Ammon, and with them other beside the Ammonites, came against Jehoshaphat to battle. Then there came some that told Jehoshaphat, saying, There cometh a great multitude against thee from beyond the sea on this side Syria; and, behold, they be in Hazazon-tamar, which is En-gedi. And Jehoshaphat feared, and set himself to seek the Lord, and proclaimed a fast throughout all Judah. And Judah gathered themselves together, to ask help of the Lord: even out of all the cities of Judah they came to seek the Lord.
"And Jehoshaphat stood in the congregation of Judah and Jerusalem, in the house of the Lord, before the new court, And said, O Lord God of our fathers, art not thou God in heaven? and rulest not thou over all the kingdoms of the heathen? and in thine hand is there not power and might, so that none is able to withstand thee? Art not thou our God, who didst drive out the inhabitants of this land before thy people Israel, and gavest it to the seed of Abraham thy friend for ever? And they dwelt therein, and have built thee a sanctuary therein for thy name, saying, If, when evil cometh upon us, as the sword, judgment, or pestilence, or famine, we stand before this house, and in thy presence, (for thy name is in this house,) and cry unto thee in our affliction, then thou wilt hear and help. And now, behold, the children of Ammon and Moab and mount Seir, whom thou wouldest not let Israel invade, when they came out of the land of Egypt, but they turned from them, and destroyed them not; Behold, I say, how they reward us, to come to cast us out of thy possession, which thou hast given us to inherit. O our God, wilt thou not judge them? for we have no might against this great company that cometh against us; neither know we what to do: but our eyes are upon thee. And all Judah stood before the Lord, with their little ones, their wives, and their children.
"Then upon Jahaziel the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah, a Levite of the sons of Asaph, came the Spirit of the Lord in the midst of the congregation; And he said, Hearken ye, all Judah, and ye inhabitants of Jerusalem, and thou king Jehoshaphat, Thus saith the Lord unto you, Be not afraid nor dismayed by reason of this great multitude; for the battle is not yours, but God’s. To morrow go ye down against them: behold, they come up by the cliff of Ziz; and ye shall find them at the end of the brook, before the wilderness of Jeruel. Ye shall not need to fight in this battle: set yourselves, stand ye still, and see the salvation of the Lord with you, O Judah and Jerusalem: fear not, nor be dismayed; to morrow go out against them: for the Lord will be with you. And Jehoshaphat bowed his head with his face to the ground: and all Judah and the inhabitants of Jerusalem fell before the Lord, worshipping the Lord. And the Levites, of the children of the Kohathites, and of the children of the Korhites, stood up to praise the Lord God of Israel with a loud voice on high.
"And they rose early in the morning, and went forth into the wilderness of Tekoa: and as they went forth, Jehoshaphat stood and said, Hear me, O Judah, and ye inhabitants of Jerusalem; Believe in the Lord your God, so shall ye be established; believe his prophets, so shall ye prosper. And when he had consulted with the people, he appointed singers unto the Lord, and that should praise the beauty of holiness, as they went out before the army, and to say, Praise the Lord; for his mercy endureth for ever.
"And when they began to sing and to praise, the Lord set ambushments against the children of Ammon, Moab, and mount Seir, which were come against Judah; and they were smitten. For the children of Ammon and Moab stood up against the inhabitants of mount Seir, utterly to slay and destroy them: and when they had made an end of the inhabitants of Seir, every one helped to destroy another. And when Judah came toward the watch tower in the wilderness, they looked unto the multitude, and, behold, they were dead bodies fallen to the earth, and none escaped. And when Jehoshaphat and his people came to take away the spoil of them, they found among them in abundance both riches with the dead bodies, and precious jewels, which they stripped off for themselves, more than they could carry away: and they were three days in gathering of the spoil, it was so much.
"And on the fourth day they assembled themselves in the valley of Berachah; for there they blessed the Lord: therefore the name of the same place was called, The valley of Berachah, unto this day. Then they returned, every man of Judah and Jerusalem, and Jehoshaphat in the forefront of them, to go again to Jerusalem with joy; for the Lord had made them to rejoice over their enemies. And they came to Jerusalem with psalteries and harps and trumpets unto the house of the Lord. And the fear of God was on all the kingdoms of those countries, when they had heard that the Lord fought against the enemies of Israel. So the realm of Jehoshaphat was quiet: for his God gave him rest round about." (2 Chronicles 20:1-30)
God fights the battles fo Enoch
"And so great was the faith of Enoch that he led the people of God, and their enemies came to battle against them; and he spake the word of the Lord, and the earth trembled, and the mountains fled, even according to his command; and the rivers of water were turned out of their course; and the roar of the lions was heard out of the wilderness; and all nations feared greatly, so powerful was the word of Enoch, and so great was the power of the language which God had given him.
"There also came up a land out of the depth of the sea, and so great was the fear of the enemies of the people of God, that they fled and stood afar off and went upon the land which came up out of the depth of the sea. And the giants of the land, also, stood afar off; and there went forth a curse upon all people that fought against God; And from that time forth there were wars and bloodshed among them; but the Lord came and dwelt with his people, and they dwelt in righteousness.
"The fear of the Lord was upon all nations, so great was the glory of the Lord, which was upon his people. And the Lord blessed the land, and they were blessed upon the mountains, and upon the high places, and did flourish. And the Lord called his people Zion, because they were of one heart and one mind, and dwelt in righteousness; and there was no poor among them." (Moses 7:13-18)
I will fight your battles
"For behold, I do not require at their hands to fight the battles of Zion; for, as I said in a former commandment, even so will I fulfil—I will fight your battles. Behold, the destroyer I have sent forth to destroy and lay waste mine enemies; and not many years hence they shall not be left to pollute mine heritage, and to blaspheme my name upon the lands which I have consecrated for the gathering together of my saints." (D&C 105:14-15)
God fights Elisha's battles, Elisha spares and feeds his enemies
"And when the servant of the man of God was risen early, and gone forth, behold, an host compassed the city both with [Syrian] horses and chariots. And his servant said unto him, Alas, my master! how shall we do? And he answered, Fear not: for they that be with us are more than they that be with them. And Elisha prayed, and said, Lord, I pray thee, open his eyes, that he may see. And the Lord opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha.
"And when they came down to him, Elisha prayed unto the Lord, and said, Smite this people, I pray thee, with blindness. And he smote them with blindness according to the word of Elisha. And Elisha said unto them, This is not the way, neither is this the city: follow me, and I will bring you to the man whom ye seek. But he led them to Samaria.
"And it came to pass, when they were come into Samaria, that Elisha said, Lord, open the eyes of these men, that they may see. And the Lord opened their eyes, and they saw; and, behold, they were in the midst of Samaria. And the king of Israel said unto Elisha, when he saw them, My father, shall I smite them? shall I smite them? And he answered, Thou shalt not smite them: wouldest thou smite those whom thou hast taken captive with thy sword and with thy bow? set bread and water before them, that they may eat and drink, and go to their master. And he prepared great provision for them: and when they had eaten and drunk, he sent them away, and they went to their master. So the bands of Syria came no more into the land of Israel." (2 Kings 6:15-23)
"In spite of our delight in defining ourselves as modern, and our tendency to think we possess a sophistication that no people in the past ever had—in spite of these things, we are, on the whole, an idolatrous people—a condition most repugnant to the Lord.
"We are a warlike people, easily distracted from our assignment of preparing for the coming of the Lord. When enemies rise up, we commit vast resources to the fabrication of gods of stone and steel—ships, planes, missiles, fortifications—and depend on them for protection and deliverance. When threatened, we become antienemy instead of pro-kingdom of God; we train a man in the art of war and call him a patriot, thus, in the manner of Satan’s counterfeit of true patriotism, perverting the Savior’s teaching:
'Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; That ye may be the children of your Father which is in heaven.' (Matt. 5:44–45.)
"We forget that if we are righteous the Lord will either not suffer our enemies to come upon us—and this is the special promise to the inhabitants of the land of the Americas (see 2 Ne. 1:7)—or he will fight our battles for us (Ex. 14:14; D&C 98:37, to name only two references of many). This he is able to do, for as he said at the time of his betrayal, 'Thinkest thou that I cannot now pray to my Father, and he shall presently give me more than twelve legions of angels?' (Matt. 26:53.) We can imagine what fearsome soldiers they would be. King Jehoshaphat and his people were delivered by such a troop (see 2 Chr. 20), and when Elisha’s life was threatened, he comforted his servant by saying, 'Fear not: for they that be with us are more than they that be with them' (2 Kgs. 6:16). The Lord then opened the eyes of the servant, 'And he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha.' (2 Kgs. 6:17.)
"Enoch, too, was a man of great faith who would not be distracted from his duties by the enemy:
'And so great was the faith of Enoch, that he led the people of God, and their enemies came to battle against them; and he spake the word of the Lord, and the earth trembled, and the mountains fled, even according to his command; and the rivers of water were turned out of their course; and the roar of the lions was heard out of the wilderness; and all nations feared greatly, so powerful was the word of Enoch.' (Moses 7:13.)
"What are we to fear when the Lord is with us? Can we not take the Lord at his word and exercise a particle of faith in him? Our assignment is affirmative: to forsake the things of the world as ends in themselves; to leave off idolatry and press forward in faith; to carry the gospel to our enemies, that they might no longer be our enemies.
"We must leave off the worship of modern-day idols and a reliance on the 'arm of flesh,' for the Lord has said to all the world in our day, 'I will not spare any that remain in Babylon.'" (D&C 64:24.)" (Spencer W. Kimball, The False Gods We Worship, Ensign, June 1976)
