I just read a wonderful article by David Csinos, the author of Children's Ministry that Fits, and Brian McClaren about involving children in social justice that I want to pass on to you. It's called:
The authors eloquently express a value that is very dear to me. Faith leads to action. Instead of locking our children in a golden tower to protect them, we can empower them to join God in renewing the world. We can show them that the world is not a scary place, but rather a place that is at times beautiful and at times fragile, hurting, and broken. A place that needs God. A place that needs his children to do his work in bringing lasting change.
Please read and let me know your thoughts!
