Prodigal Son Messy Church prayer response

As one of our craft activities at Messy Church we built a house out of cardboard boxes.  It turned out brilliantly and even had a door.  The younger children especially liked hiding inside it!  In the celebration section we used the house for a prayer response.  After telling the story and having a short talk about forgiveness, we talked about God forgiving us for the wrong things we have done if we come to him and say sorry, because He loves us so much.  We asked everyone to think of something they'd done that they'd like to say sorry for and then we played some music and people came forward to put a heart shaped post it note on the house as a symbol that God loved them, forgave them and welcomed them into his house.  Luckily the house stayed standing throughout!!
