We Don't Need Sunday School?

"Our children go to our Lutheran Day School."
"We go to church as a family every Sunday."
"We have mealtime devotions."
"We read and discuss Bible stories every night with our children before going to bed."
"We don't need to participate in Sunday School do we?"

My coworker Peter said it well, "Can we ever get too much of God's Word?"

Thanks for teaching God's children His Word in Sunday School!
