Right now we use a value based curriculum. What that means is that every month we teach the kids a different biblical value (obedience, respect, perseverance, etc.). I have noticed that some of the kids have come to the conclusion that performing the values is what God requires of them. I have tried to steer them away from that belief by reinforcing the concept of their need for Christ before any good works are possible and that good works are not the point anyway. I want them to know that their purpose is to glorify God and enjoy Him forever and that He is the greatest treasure, not a list of virtues that they should run after.
Anyway, if you know of a good God centered curriculum that can help us lead our kids to a right understanding of who God is and who they were created to be, let me know.
