Child
A child is a young boy or girl in the care of parents, older than a suckling or an infant, but not yet an adolescent. "Children" are sometimes used as a name for a large group of descendants of one person, such as the Children of Israel, or even all human beings as the Children of Men. A child represents innocence and charity, where innocence is the willingness to be led, and charity is love. This is why Jesus blessed them and suggested that we all become like children in order to enter heaven.
Micah 4:1-3
1
But in the latter days, it will happen that the mountain of Yahweh's temple will be established on the top of the mountains, and it will be exalted above the hills; and peoples will stream to it.
2
Many nations will go and say, "Come, and let us go up to the mountain of Yahweh, and to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths." For out of Zion will go forth the law, and the word of Yahweh from Jerusalem;
3
and he will judge between many peoples, and will decide concerning strong nations afar off. They will beat their swords into plowshares, and their spears into pruning hooks. Nation will not lift up sword against Nation, neither will they learn war any more.
