Then you are in a position to teach. Every once and a while you get a little reminder of what God has been up to with His word. The Word of God has a way of breaking through and getting in. I'm a firm believer in having the little ones in church, in the Liturgy. Even the littlest ones.

Jesus says they are the picture of what the church ought to look like. I know takes a great deal of patience, but it's well worth the effort, even if it means a few squirmy Sundays. We grew into it. St. Paul reminded Timothy of how he had been acquainted with the Scriptures since the time of his infancy, before he could read. Most things we give our children, they will grow out of all too quickly.
