Verse 2. And the whole power of the Internal shall be communicated to the External; and the External shall be prepared, by the acknowledgement of the Lord, and influx from Him through the heavens, for such worship; while the conjunction of truth with good shall be effected, and thus conjunction with the Lord.

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.
