Arcana Coelestia # 3334
3334. 'And he rose up' means a consequent raising up. This is clear from the meaning of 'rising up' wherever it is used, as embodying a raising up, dealt with in 2401, 2785, 2912, 2927. A person is said to be raised up when he is being perfected as regards spiritual and celestial things, that is, as regards truth which belongs to faith, and as regards good which belongs to love and charity, 3171.
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.
