Some times we know that we have been naughty, even before Mum and Dad tell us off. We know we have done wrong because we feel bad inside. We call this feeling guilty, God wants us to say sorry and make things better. God is amazing and always forgives us, He helps us put things right again.
When I know I have done something wrong, help me to say sorry, and put things right.
Take a look at psalm 51, it is a song about saying sorry.
Jesus uses stories about washing to show how to say sorry and be forgiven. Maybe next time you wash your hands, think about the things you could say sorry for.
