I teach a Sunday school program to 3 and 4 year old. A fun group but sometimes a little difficult to work with in a big group and all stay on task.
They definitely are the miracle of today. All the kids sat so good for the story and answered all the questions about the story I had quizzed them on. They also all participated in making the craft, even Jacob! From start to finish! They made dusting mitts to help their parents dust around the house. This was to teach we all need to help out in cleaning, odd for bible group you might think but it was tagging into the story of Jesus washing the disciples feet the night of the last supper.
It feels so good to teach these little people about God and that they understand it and are so able to just soak it in and have faith that God has done things for us even though we can't cognitively explain it sometimes.
