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.
Zephaniah 3:14-17
14
Sing, daughter of Zion! Shout, Israel! Be glad and rejoice with all your heart, daughter of Jerusalem.
15
Yahweh has taken away your judgments. He has thrown out your enemy. The King of Israel, Yahweh, is in the midst of you. You will not be afraid of evil any more.
16
In that day, it will be said to Jerusalem, "Don't be afraid, Zion. Don't let your hands be weak."
17
Yahweh, your God, is in the midst of you, a mighty one who will save. He will rejoice over you with joy. He will calm you in his love. He will rejoice over you with singing.
