We can learn a lot from each other. Share the knowledge.
You've been teaching children's Sunday school for the last twenty years, the last thing you need is some young whipper snapper telling you how to run a Sunday school classroom. Or you're young, energetic, and creative. You don't want to do things the same old way.
No man, or woman, is an island, we can all benefit from the experience of others.
Hearing about a new, highly effective idea may just be the spark you needed to regain your enthusiasm for teaching. If we're honest with ourselves, we realize that we all go through dry periods. Getting together, either in person or online, can help get us out of a slump and re-ignite the passion we once had for teaching.
Maybe you're on top of your game, the kids love your lessons, the pastor wants to hire you to be the new children's minister, parents adore you, everything is going right. Should you still be interested in a support group? You bet! In fact, support groups may be one of the reasons why you are where you are in your children's ministry. If you have methods that work, really work, shouldn't you share these same ideas with other children's Sunday school teachers? Together we can we can do so much more than we could ever do alone.
