If a child can sin then a child can be saved.
You teach children—you are not dishonored by it. Some say you are nothing but a Sunday School teacher, but you are a noble person, holding an honorable office, and having illustrious predecessors. We love to see persons of some standing in society take an interest in Sunday Schools. One great fault in many of our churches is that the children are left to the young people to take care of—the older members, who have more wisdom, take very little notice of them; and very often the wealthier members of the church stand aside as if the teaching of the poor were not (as indeed it is) the special business of the rich.
Charles Spurgeon
