Micah it one of those prophets who saw the latter days. He wrote about the responsibility as children of Israel and members of the church, which we have to carry the gospel to the world. Micah teaches by comparison and similitudes. He presents the task of missionary work as gather the wheat and separating it from the chaff. This was a task where the oxen were used.
Micah: 4 11 ¶Now also many nations are gathered against thee, that say, Let her be defiled, and let our eye look upon Zion.
12 But they know not the thoughts of the Lord, neither understand they his counsel: for he shall gather them as the sheaves into the floor.
13 Arise and thresh, O daughter of Zion: for I will make thine horn iron, and I will make thy hoofs brass: and thou shalt beat in pieces many people: and I will consecrate their gain unto the Lord, and their substance unto the Lord of the whole earth.He further talks about missionary work, comparing those who have the gospel as The Dews of heaven, who water all the grass. He then compares them to a lion among ship. When we open our mouths and invite others to Christ, we will be as the lion who none can oppose.
Micah 5: 7 And the remnant of Jacob shall be in the midst of many people as a dew from the Lord, as the showers upon the grass, that tarrieth not for man, nor waiteth for the sons of men.
8 ¶And the remnant of Jacob shall be among the Gentiles in the midst of many people as a lion among the beasts of the forest, as a young lion among the flocks of sheep: who, if he go through, both treadeth down, and teareth in pieces, and none can deliver.
M. Russel Ballard talked about the confidence that comes when combining missionary work and prayer.
In 1842 the Prophet Joseph Smith, in the Wentworth letter Joseph Smith made a similar statement. He declared, “No unhallowed hand can stop the work from progressing; persecutions may rage, mobs may combine, armies may assemble, calumny may defame, but the truth of God will go forth boldly, nobly, and independent, till it has penetrated every continent, visited every clime, swept every country, and sounded in every ear, till the purposes of God shall be accomplished, and the Great Jehovah shall say the work is done” (History of the Church, 4:540).
