Today the theme for the Jesse Tree was "The New Covenant". The symbol is a heart with writing on it - because in the reading today, we hear that God will write the new covenant on our hearts. The readings are: Jeremiah 31:31-33 and Hebrews 9:13-15.
I needed to explain to the children what a covenant was. And we went over briefly that God had made covenants with his people before - with Abraham and Moses. And when God came to us as Jesus he was making another covenant with us.
