Give it a try sometime. Your kids will love seeing your drawing as it progresses throughout the sermon. It's not uncommon for us to be passing artwork back and forth down the pew. Don't worry - it's not distracting. In fact, I think it gets the kids all the more engaged in listening and understanding the sermon.
Below is a sample of illustrating the sermon that my 2 of my kids did this past Sunday. The sermon was on Hannah. Since it was a narrative, it made it a very easy one to illustrate. First, is my 7 year old daughter's illustration. I love that she labeled Hannah as #1 and Peninnah as #2! I also like her drawing on the left where Peninnah is saying unkind things to Hannah, who is crying.
1) Why was Hannah barren? It was not a punishment from sin but rather so God could display His glory.
2) What person made it more difficult for Hannah to deal with having no children? Peninnah, Elkanah's other wife.
3) What did Peninnah use to hurt Hannah? Her words.
4) What are your 2 choices when you experience a difficult time? Turn to God or turn away from God.
5) When Hannah prayed, what did she call herself? a servant
6) What part of Hannah's story impressed you most?
7) What's something hard that you might face and how could you plan to respond?
Be creative in helping your children take notes in church. Taking notes isn't for everyone but I believe it can do wonders for children in helping them engage in the preaching of God's Word.
