To help kids understand the meaning of prayer, have them each create their own DIY Prayer Jar. This activity can go along with a discussion about what prayer is, why we pray, and specific Bible versus related to prayer. You can also adjust the craft to go along with your lesson. If you are teaching about how to be thankful, create Gratitude Jars. To teach them to be mindful of all the positives that God has given us, create a Blessing Jar.
