In Jesus’ teaching children represented the Kingdom of Heaven. Jesus said, “Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven.” Becoming like children is a metaphor that used for what in other spiritual traditions is called enlightenment, awakening, nirvana, liberation, self-realization or any number of other terms. Children know naturally what adults have forgotten.  He need to remember what we have forgotten.
