This is the beginning of a new part of the story that runs through [Matthew 18:35](../18/35.md), where Jesus teaches about life inthe kingdom of heaven. Here, Jesus uses a little child to teach the disciples.
The phrase "kingdom of heaven" refers to God's rule as king. This phrase is used only in the book of Matthew. If possible, keep "heaven" in your translation. Alternate translation: "in God's kingdom" or "when our God in heaven establishes his rule on earth" (See: [[rc://en/ta/man/translate/figs-metonymy]])
